DESCRIPTION

       Cabal is the standard package system for Haskell software.  It  helps  people  to  configure,  build  and
       install Haskell software and to distribute it easily to other users and developers.

       The  command  line cabal tool (also referred to as cabal-install) helps with installing existing packages
       and developing new packages.  It can be used to work with local packages  or  to  install  packages  from
       online  package archives, including automatically installing dependencies. By default it is configured to
       use Hackage, which is Haskell's  central  package  archive  that  contains  thousands  of  libraries  and
       applications in the Cabal package format.

COMMANDS

       cabal list

       Usage: cabal list [FLAGS]
          or: cabal list [FLAGS] STRINGS

       List all packages, or all packages matching one of the search strings.

       If there is a sandbox in the current directory  and  config:ignore-sandbox  is  False,  use  the  sandbox
       package  database. Otherwise, use the package database specified with --package-db. If not specified, use
       the user package database.

       Examples:
         cabal list pandoc
           Will find pandoc, pandoc-citeproc, pandoc-lens, ...

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --installed
                     Only print installed packages

              --simple-output
                     Print in a easy-to-parse format

              --package-db DB
                     Append the given package database to  the  list  of  package  databases  used  (to  satisfy
                     dependencies  and  register  into). May be a specific file, 'global' or 'user'. The initial
                     list is ['global'], ['global', 'user'], or ['global', $sandbox], depending on context.  Use
                     'clear' to reset the list to empty. See the user guide for details.

       cabal info

       Usage: cabal info [FLAGS] PACKAGES

       If  there  is  a  sandbox  in  the  current directory and config:ignore-sandbox is False, use the sandbox
       package database. Otherwise, use the package database specified with --package-db. If not specified,  use
       the user package database.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --package-db DB
                     Append  the  given  package  database  to  the  list  of package databases used (to satisfy
                     dependencies and register into). May be a specific file, 'global' or  'user'.  The  initial
                     list  is ['global'], ['global', 'user'], or ['global', $sandbox], depending on context. Use
                     'clear' to reset the list to empty. See the user guide for details.

       cabal fetch

       Usage: cabal fetch [FLAGS] PACKAGES

       Note that it currently is not possible to fetch the dependencies for a package in the current directory.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --dependencies, --deps
                     Resolve and fetch dependencies (default)

              --no-dependencies, --no-deps
                     Ignore dependencies

              --dry-run
                     Do not install anything, only print what would be installed.

              --enable-tests
              --disable-tests
                     dependency checking and compilation for test suites listed in the package description file.

              --enable-benchmarks
              --disable-benchmarks
                     dependency checking and compilation for benchmarks listed in the package description file.

              --solver SOLVER
                     Select dependency solver to use (default: modular). Choices: modular.

              --max-backjumps NUM
                     Maximum number of backjumps allowed while solving (default: 4000). Use a negative number to
                     enable unlimited backtracking. Use 0 to disable backtracking completely.

              --reorder-goals
              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may
                     make backtracking faster for some packages.

              --count-conflicts
              --no-count-conflicts
                     Try to speed up solving by preferring goals  that  are  involved  in  a  lot  of  conflicts
                     (default).

              --minimize-conflict-set
              --no-minimize-conflict-set
                     When  there  is no solution, try to improve the error message by finding a minimal conflict
                     set (default: false). May increase run time significantly.

              --independent-goals
              --no-independent-goals
                     Treat several goals on the command line as independent. If several goals depend on the same
                     package, different versions can be chosen.

              --shadow-installed-packages
              --no-shadow-installed-packages
                     If multiple package instances of the same version are  installed,  treat  all  but  one  as
                     shadowed.

              --strong-flags
              --no-strong-flags
                     Do not defer flag choices (this used to be the default in cabal-install <= 1.20).

              --allow-boot-library-installs
              --no-allow-boot-library-installs
                     Allow cabal to install base, ghc-prim, integer-simple, integer-gmp, and template-haskell.

              --reject-unconstrained-dependencies none|all
                     Require  these  packages  to  have constraints on them if they are to be selected (default:
                     none).

       cabal get

       Usage: cabal get [PACKAGES]

       Creates a local copy of a package's source code. By default it gets the source tarball and unpacks it  in
       a local subdirectory. Alternatively, with -s it will get the code from the source repository specified by
       the package.

       Examples:
         cabal get hlint
           Download the latest stable version of hlint;
         cabal get lens --source-repository=head
           Download the source repository (i.e. git clone from github).

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              -d, --destdir PATH
                     Where to place the package source, defaults to the current directory.

              -s, --source-repository [[head|this|...]]
                     Copy the package's source repository (ie git clone, darcs get, etc as appropriate).

              --index-state STATE
                     Use  source  package  index state as it existed at a previous time. Accepts unix-timestamps
                     (e.g. '@1474732068'), ISO8601  UTC  timestamps  (e.g.  '2016-09-24T17:47:48Z'),  or  'HEAD'
                     (default:  'HEAD').  This determines which package versions are available as well as .cabal
                     file revision is selected (unless --pristine is used).

              --pristine
                     Unpack the original pristine tarball, rather than updating the .cabal file with the  latest
                     revision from the package archive.

       cabal check

       Usage: cabal check [FLAGS]

       Expects a .cabal package file in the current directory.

       The checks correspond to the requirements to packages on Hackage. If no errors and warnings are reported,
       Hackage will accept this package.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

       cabal upload

       Usage: cabal upload [FLAGS] TARFILES

       You can store your Hackage login in the ~/.cabal/config file Relevant global configuration keys:
         username
         password

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --publish
                     Publish the package instead of uploading it as a candidate.

              -d, --documentation
                     Upload  documentation  instead  of a source package. By default, this uploads documentation
                     for a package candidate. To upload documentation for  a  published  package,  combine  with
                     --publish.

              -u, --username USERNAME
                     Hackage username.

              -p, --password PASSWORD

                     Command to get Hackage password.

       cabal report

       Usage: cabal report [FLAGS]

              -u, --username USERNAME
                     Hackage username.

              -p, --password PASSWORD
                     Hackage password.

       cabal init

       Usage: cabal init [FLAGS]

       Create a .cabal, Setup.hs, and optionally a LICENSE file.

       Calling  init  with  no  arguments  creates  an  executable,  guessing  as  many options as possible. The
       interactive mode can be invoked by the -i/--interactive flag, which will try to guess as much as possible
       and prompt you for the rest. You can change init to always be interactive by setting the interactive flag
       in your configuration file. Command-line arguments are provided for scripting purposes.

       Flags:
              -i, --interactive
              -n, --non-interactive

       defined and not commented out) and the default config of the new version.

       init:  Creates a new config file at either ~/.cabal/config or as specified by --config-file, if given. An
       existing file won't be overwritten unless -f or --force is given.   diff:  Shows  a  pseudo-diff  of  the
       user's  ~/.cabal/config  file  and the default configuration that would be created by cabal if the config
       file did not exist.  update: Applies the pseudo-diff to  the  configuration  that  would  be  created  by
       default, and write the result back to ~/.cabal/config.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              -f, --force
                     Overwrite the config file if it already exists.

              -a, --augment CONFIGLINE
                     Additional setting to augment the config file (replacing a previous setting if it existed).

       cabal gen-bounds

       Usage: cabal gen-bounds [FLAGS]

       Generates  bounds  for all dependencies that do not currently have them.  Generated bounds are printed to
       stdout. You can then paste them into your

       Flags:

       commands (such as 'build',

       The configure command also checks that the project configuration will work.  In particular it checks that
       there is a consistent set of dependencies for the project as a whole.

       The  'cabal.project.local'  file  persists  across  'clean'  but  is  overwritten  on the next use of the

       cabal new-configure

       Usage: cabal new-configure [FLAGS]

       Adjust how the project is built by setting additional package flags and other flags.

       The  configuration  options  are  written  to  the  'cabal.project.local' file (or configuration from the
       'cabal.project' file (if any). This combination is used  as  the  project  configuration  for  all  other
       commands (such as 'new-build',

       The  new-configure command also checks that the project configuration will work.  In particular it checks
       that there is a consistent set of dependencies for the project as a whole.

       The 'cabal.project.local' file persists across 'new-clean' but is overwritten on  the  next  use  of  the
       'new-configure' command. The intention is that the

       It  is  never necessary to use the 'new-configure' command. It is merely a convenience in cases where you
       do not want to specify flags to 'new-build' (and other commands) every time and yet do not want to  alter
       the 'cabal.project' persistently.

       cabal v2-configure

       Usage: cabal v2-configure [FLAGS]

       Adjust how the project is built by setting additional package flags and other flags.

       The  configuration  options  are  written  to  the  'cabal.project.local' file (or configuration from the
       'cabal.project' file (if any). This combination is used  as  the  project  configuration  for  all  other
       commands (such as 'v2-build',

       The  v2-configure  command also checks that the project configuration will work.  In particular it checks
       that there is a consistent set of dependencies for the project as a whole.

       The 'cabal.project.local' file persists across 'v2-clean' but is overwritten  on  the  next  use  of  the
       'v2-configure' command. The intention is that the

       It is never necessary to use the 'v2-configure' command. It is merely a convenience in cases where you do
       not  want to specify flags to 'v2-build' (and other commands) every time and yet do not want to alter the
       'cabal.project' persistently.

       Examples:
         cabal v2-configure --with-compiler ghc-7.10.3
           Adjust the project configuration to use the given compiler
           program and check the resulting configuration works.
         cabal v2-configure
           Reset the local configuration to empty and check the overall
           project configuration works.

       Note: this command is part of the new project-based system (aka nix-style local builds).  These  features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details  and  advice  on  what  you  can  expect to work. If you encounter problems please file issues at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may

              --no-reinstall
                     Install even if it means installing the same version again.

       cabal v2-update

       Usage: cabal v2-update [FLAGS] [REPOS]

       For all known remote repositories, download the package list.

       REPO  has  the format <repo-id>[,<index-state>] where index-state follows the same format and syntax that
       is supported by the --index-state flag.

       Examples:
         cabal v2-update
           Download the package list for all known remote repositories.

         cabal new update hackage.haskell.org head.hackage
           Download hackage.haskell.org and head.hackage
           head.hackage must be a known repo-id. E.g. from
           your cabal.project(.local) file.

       Note: this command is part of the new project-based system (aka nix-style local builds).  These  features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details  and  advice  on  what  you  can  expect to work. If you encounter problems please file issues at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

       cabal build

       Usage: cabal build [TARGETS] [FLAGS]

       Build  one or more targets from within the project. The available targets are the packages in the project
       as well as individual components within those packages, including libraries, executables, test-suites  or
       benchmarks.  Targets  can be specified by name or location. If no target is specified then the default is
       to build the package in the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

              --no-avoid-reinstalls
                     Do not select versions that would destructively overwrite installed packages.

              --no-upgrade-dependencies
                     Pick  the  latest  version  for  all  dependencies, rather than trying to pick an installed

       cabal new-build

       Usage: cabal new-build [TARGETS] [FLAGS]

       Build  one or more targets from within the project. The available targets are the packages in the project
       as well as individual components within those packages, including libraries, executables, test-suites  or
       benchmarks.  Targets  can be specified by name or location. If no target is specified then the default is
       to build the package in the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       cabal v2-build

       Usage: cabal v2-build [TARGETS] [FLAGS]

       Build  one or more targets from within the project. The available targets are the packages in the project
       as well as individual components within those packages, including libraries, executables, test-suites  or
       benchmarks.  Targets  can be specified by name or location. If no target is specified then the default is
       to build the package in the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       Examples:
         cabal v2-build
           Build the package in the current directory or all packages in the project
         cabal v2-build pkgname
           Build the package named pkgname in the project
         cabal v2-build ./pkgfoo
           Build the package in the ./pkgfoo directory
         cabal v2-build cname
           Build the component named cname in the project
         cabal v2-build cname --enable-profiling
           Build the component in profiling mode (including dependencies as needed)

       Note: this command is part of the new project-based system (aka nix-style local builds).  These  features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details  and  advice  on  what  you  can  expect to work. If you encounter problems please file issues at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

       cabal repl

       Usage: cabal repl [TARGET] [FLAGS]

       Open an interactive session for a component within the project. The available targets are the same as for
       the  'build'  command:  individual  components  within  packages  in  the  project,  including libraries,
       executables, test-suites or benchmarks. Packages  can  also  be  specified  in  which  case  the  library
       component  in  the  package  will be used, or the (first listed) executable in the package if there is no
       library.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       cabal new-repl

       Usage: cabal new-repl [TARGET] [FLAGS]

       Open an interactive session for a component within the project. The available targets are the same as for
       the  'new-build'  command:  individual  components  within  packages in the project, including libraries,
       executables, test-suites or benchmarks. Packages  can  also  be  specified  in  which  case  the  library
       component  in  the  package  will be used, or the (first listed) executable in the package if there is no
       library.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       cabal v2-repl

       Usage: cabal v2-repl [TARGET] [FLAGS]

       Open an interactive session for a component within the project. The available targets are the same as for
       the  'v2-build'  command:  individual  components  within  packages  in the project, including libraries,
       executables, test-suites or benchmarks. Packages  can  also  be  specified  in  which  case  the  library
       component  in  the  package  will be used, or the (first listed) executable in the package if there is no
       library.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       Examples, open an interactive session:
         cabal v2-repl
           for the default component in the package in the current directory
         cabal v2-repl pkgname
           for the default component in the package named 'pkgname'
         cabal v2-repl ./pkgfoo
           for the default component in the package in the ./pkgfoo directory
         cabal v2-repl cname
           for the component named 'cname'
         cabal v2-repl pkgname:cname
           for the component 'cname' in the package 'pkgname'

         cabal v2-repl --build-depends lens
           add the latest version of the library 'lens' to the default component (or no componentif there is  no
       project present)
         cabal v2-repl --build-depends "lens >= 4.15 && < 4.18"
           add  a version (constrained between 4.15 and 4.18) of the library 'lens' to the default component (or
       no component if there is no project present) Note: this command is part of the new  project-based  system
       (aka    nix-style    local    builds).    These    features   are   currently   in   beta.   Please   see
       http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice  on  what  you
       can     expect     to     work.     If     you    encounter    problems    please    file    issues    at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may

              --reinstall
              --no-reinstall
                     Install even if it means installing the same version again.

       cabal v2-freeze

       Usage: cabal v2-freeze [FLAGS]

       The project configuration is frozen so that it will be reproducible in future.

       The  precise dependency configuration for the project is written to the specified). This file extends the
       configuration from the 'cabal.project' file and thus is used as the project configuration for  all  other
       commands (such as

       The freeze file can be kept in source control. To make small adjustments it may be edited manually, or to
       make  bigger  changes you may wish to delete the file and re-freeze. For more control, one approach is to
       try variations using once you have a satisfactory solution to freeze it  using  the  'v2-freeze'  command
       with the same set of flags.

       Examples:
         cabal v2-freeze
           Freeze the configuration of the current project

         cabal v2-build --dry-run --constraint="aeson < 1"
           Check what a solution with the given constraints would look like
         cabal v2-freeze --constraint="aeson < 1"
           Freeze a solution using the given constraints

       Note:  this  command is part of the new project-based system (aka nix-style local builds). These features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details and advice on what you can expect to work. If  you  encounter  problems  please  file  issues  at
       https://github.com/haskell/cabal/issues  and  if you have any time to get involved and help with testing,
       fixing bugs etc then that is very much appreciated.

              --max-backjumps NUM
                     Maximum number of backjumps allowed while solving (default: 4000). Use a negative number to
                     enable unlimited backtracking. Use 0 to disable backtracking completely.

              --reorder-goals
              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may
                     make backtracking faster for some packages.

                     set (default: false). May increase run time significantly.

              --independent-goals
              --no-independent-goals
                     Treat several goals on the command line as independent. If several goals depend on the same

              --no-shadow-installed-packages
                     If multiple package instances of the same version are  installed,  treat  all  but  one  as

                     Allow cabal to install base, ghc-prim, integer-simple, integer-gmp, and template-haskell.

              --reject-unconstrained-dependencies none|all
                     Require  these  packages  to  have constraints on them if they are to be selected (default:
                     none).

              --reinstall
              --no-reinstall
                     Install even if it means installing the same version again.

              --avoid-reinstalls
              --no-avoid-reinstalls
                     Do not select versions that would destructively overwrite installed packages.

              --force-reinstalls
              --no-force-reinstalls
                     Reinstall packages even if they will most likely break other installed packages.

              --no-upgrade-dependencies
                     Pick the latest version for all dependencies, rather  than  trying  to  pick  an  installed

       cabal v2-haddock

       Usage: cabal v2-haddock [FLAGS] TARGET

       Build Haddock documentation for the specified packages within the project.

       Any package in the project can be specified. If no package is specified, the  default  is  to  build  the
       documentation  for  the package in the current directory. The default behaviour is to build documentation
       for the exposed modules of the library component (if any). This can be changed with the

       Currently, documentation for dependencies is NOT built. This behavior may change in future.

       Additional configuration flags can be specified  on  the  command  line  and  these  extend  the  project
       configuration from the 'cabal.project',

       Examples:
         cabal v2-haddock pkgname    Build documentation for the package named pkgname

       Note:  this  command is part of the new project-based system (aka nix-style local builds). These features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details and advice on what you can expect to work. If  you  encounter  problems  please  file  issues  at
       https://github.com/haskell/cabal/issues  and  if you have any time to get involved and help with testing,
       fixing bugs etc then that is very much appreciated.

              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may

                     none).

              --reinstall
              --no-reinstall
                     Install even if it means installing the same version again.

       cabal install

       Usage: cabal install [TARGETS] [FLAGS]

       Installs one or more packages. This is done by installing them in the store  and  symlinking/copying  the
       executables in the directory specified by the --installdir flag (`~/.cabal/bin/` by default). If you want
       the installed executables to be available globally, make sure that the PATH environment variable contains
       that directory.

       If  TARGET  is  a library, it will be added to the global environment. When doing this, cabal will try to
       build a plan that includes all the previously installed libraries. This is currently not implemented.

       cabal new-install

       Usage: cabal new-install [TARGETS] [FLAGS]

       Installs one or more packages. This is done by installing them in the store  and  symlinking/copying  the
       executables in the directory specified by the --installdir flag (`~/.cabal/bin/` by default). If you want
       the installed executables to be available globally, make sure that the PATH environment variable contains
       that directory.

       If  TARGET  is  a library, it will be added to the global environment. When doing this, cabal will try to
       build a plan that includes all the previously installed libraries. This is currently not implemented.

       cabal v2-install

       Usage: cabal v2-install [TARGETS] [FLAGS]

       Installs one or more packages. This is done by installing them in the store  and  symlinking/copying  the
       executables in the directory specified by the --installdir flag (`~/.cabal/bin/` by default). If you want
       the installed executables to be available globally, make sure that the PATH environment variable contains
       that directory.

       If  TARGET  is  a library, it will be added to the global environment. When doing this, cabal will try to
       build a plan that includes all the previously installed libraries. This is currently not implemented.

       Examples:
         cabal v2-install
           Install the package in the current directory
         cabal v2-install pkgname
           Install the package named pkgname (fetching it from hackage if necessary)
         cabal v2-install ./pkgfoo
           Install the package in the ./pkgfoo directory Note: this command is part  of  the  new  project-based
       system   (aka   nix-style   local   builds).   These   features   are   currently  in  beta.  Please  see
       http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice  on  what  you
       can     expect     to     work.     If     you    encounter    problems    please    file    issues    at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

       cabal run

       Usage: cabal run [TARGET] [FLAGS] [-- EXECUTABLE_FLAGS]

       Runs  the  specified executable-like component (an executable, a test, or a benchmark), first ensuring it
       is up to date.

       Any executable-like component in any package in the project can be specified.  A package can be specified
       if contains just one executable-like. The default is to use the package in the current  directory  if  it
       contains just one executable-like.

       Extra  arguments  can  be  passed to the program, but use '--' to separate arguments for the program from
       arguments for cabal. The executable is run in an environment where it can find its data files inplace  in
       the build tree.

       Dependencies  are  built  or rebuilt as necessary. Additional configuration flags can be specified on the
       command line and these extend the project configuration from the  'cabal.project',  'cabal.project.local'
       and other files.

       Extra  arguments  can  be  passed to the program, but use '--' to separate arguments for the program from
       arguments for cabal. The executable is run in an environment where it can find its data files inplace  in
       the build tree.

       Dependencies  are  built  or rebuilt as necessary. Additional configuration flags can be specified on the
       command line and these extend the project configuration from the  'cabal.project',  'cabal.project.local'
       and other files.

       Flags:

       cabal new-run

       Usage: cabal new-run [TARGET] [FLAGS] [-- EXECUTABLE_FLAGS]

       Runs  the  specified executable-like component (an executable, a test, or a benchmark), first ensuring it
       is up to date.

       Any executable-like component in any package in the project can be specified.  A package can be specified
       if contains just one executable-like. The default is to use the package in the current  directory  if  it
       contains just one executable-like.

       Extra  arguments  can  be  passed to the program, but use '--' to separate arguments for the program from
       arguments for cabal. The executable is run in an environment where it can find its data files inplace  in
       the build tree.

       Dependencies  are  built  or rebuilt as necessary. Additional configuration flags can be specified on the
       command line and these extend the project configuration from the  'cabal.project',  'cabal.project.local'
       and other files.

       cabal v2-run

       Usage: cabal v2-run [TARGET] [FLAGS] [-- EXECUTABLE_FLAGS]

       Runs  the  specified executable-like component (an executable, a test, or a benchmark), first ensuring it
       is up to date.

       Any executable-like component in any package in the project can be specified.  A package can be specified
       if contains just one executable-like. The default is to use the package in the current  directory  if  it
       contains just one executable-like.

       Extra  arguments  can  be  passed to the program, but use '--' to separate arguments for the program from
       arguments for cabal. The executable is run in an environment where it can find its data files inplace  in
       the build tree.

       Dependencies  are  built  or rebuilt as necessary. Additional configuration flags can be specified on the
       command line and these extend the project configuration from the  'cabal.project',  'cabal.project.local'
       and other files.

       Examples:
         cabal v2-run
           Run the executable-like in the package in the current directory
         cabal v2-run foo-tool
           Run the named executable-like (in any package in the project)
         cabal v2-run pkgfoo:foo-tool
           Run the executable-like 'foo-tool' in the package 'pkgfoo'
         cabal v2-run foo -O2 -- dothing --fooflag
           Build with '-O2' and run the program, passing it extra arguments.

       Note:  this  command is part of the new project-based system (aka nix-style local builds). These features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details and advice on what you can expect to work. If  you  encounter  problems  please  file  issues  at
       https://github.com/haskell/cabal/issues  and  if you have any time to get involved and help with testing,
       fixing bugs etc then that is very much appreciated.

       cabal test

       Usage: cabal test [TARGETS] [FLAGS]

       Runs the specified test-suites, first ensuring they are up to date.

       Any test-suite in any package in the project can be specified. A package can be specified in  which  case
       all  the  test-suites in the package are run. The default is to run all the test-suites in the package in
       the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       To pass command-line arguments to a test suite, see the run command.

       cabal new-test

       Usage: cabal new-test [TARGETS] [FLAGS]

       Runs the specified test-suites, first ensuring they are up to date.

       Any test-suite in any package in the project can be specified. A package can be specified in  which  case
       all  the  test-suites in the package are run. The default is to run all the test-suites in the package in
       the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       To pass command-line arguments to a test suite, see the new-run command.

              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may

              --no-reinstall
                     Install even if it means installing the same version again.

       cabal v2-test

       Usage: cabal v2-test [TARGETS] [FLAGS]

       Runs the specified test-suites, first ensuring they are up to date.

       Any test-suite in any package in the project can be specified. A package can be specified in  which  case
       all  the  test-suites in the package are run. The default is to run all the test-suites in the package in
       the current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       To pass command-line arguments to a test suite, see the v2-run command.

       Examples:
         cabal v2-test
           Run all the test-suites in the package in the current directory
         cabal v2-test pkgname
           Run all the test-suites in the package named pkgname
         cabal v2-test cname
           Run the test-suite named cname
         cabal v2-test cname --enable-coverage
           Run the test-suite built with code coverage (including local libs used)

       Note: this command is part of the new project-based system (aka nix-style local builds).  These  features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details  and  advice  on  what  you  can  expect to work. If you encounter problems please file issues at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

                     list  is ['global'], ['global', 'user'], or ['global', $sandbox], depending on context. Use
                     'clear' to reset the list to empty. See the user guide for details.

       cabal v2-bench

       Usage: cabal v2-bench [TARGETS] [FLAGS]

       Runs the specified benchmarks, first ensuring they are up to date.

       Any  benchmark  in  any package in the project can be specified. A package can be specified in which case
       all the benchmarks in the package are run. The default is to run all the benchmarks in the package in the
       current directory.

       Dependencies are built or rebuilt as necessary. Additional configuration flags can be  specified  on  the
       command  line  and these extend the project configuration from the 'cabal.project', 'cabal.project.local'
       and other files.

       Examples:
         cabal v2-bench
           Run all the benchmarks in the package in the current directory
         cabal v2-bench pkgname
           Run all the benchmarks in the package named pkgname
         cabal v2-bench cname
           Run the benchmark named cname
         cabal v2-bench cname -O2
           Run the benchmark built with '-O2' (including local libs used)

       Note: this command is part of the new project-based system (aka nix-style local builds).  These  features
       are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for
       details  and  advice  on  what  you  can  expect to work. If you encounter problems please file issues at
       https://github.com/haskell/cabal/issues and if you have any time to get involved and help  with  testing,
       fixing bugs etc then that is very much appreciated.

       cabal exec

       Usage: cabal exec [FLAGS] [--] COMMAND [--] [ARGS]

       During  development  it  is  often  useful  to  run build tasks and perform one-off program executions to
       experiment with the behavior of build tools. It is convenient to run these tools in the  same  way  cabal
       itself would. The `cabal exec` command provides a way to do so.

       Compiler  tools will be configured to see the same subset of the store that builds would see. The PATH is
       modified to make all executables in  the  dependency  tree  available  (provided  they  have  been  built
       already).  Commands  are also rewritten in the way cabal itself would. For example, `cabal exec ghc` will
       consult the configuration to choose an appropriate version of ghc and to include any  ghc-specific  flags
       requested.

              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may

              --no-reinstall
                     Install even if it means installing the same version again.

       cabal new-exec

       Usage: cabal new-exec [FLAGS] [--] COMMAND [--] [ARGS]

       During  development  it  is  often  useful  to  run build tasks and perform one-off program executions to
       experiment with the behavior of build tools. It is convenient to run these tools in the  same  way  cabal
       itself would. The `cabal new-exec` command provides a way to do so.

       Compiler  tools will be configured to see the same subset of the store that builds would see. The PATH is
       modified to make all executables in  the  dependency  tree  available  (provided  they  have  been  built
       already).  Commands  are  also rewritten in the way cabal itself would. For example, `cabal new-exec ghc`
       will consult the configuration to choose an appropriate version of ghc and to  include  any  ghc-specific
       flags requested.

       cabal v2-exec

       Usage: cabal v2-exec [FLAGS] [--] COMMAND [--] [ARGS]

       During  development  it  is  often  useful  to  run build tasks and perform one-off program executions to
       experiment with the behavior of build tools. It is convenient to run these tools in the  same  way  cabal
       itself would. The `cabal v2-exec` command provides a way to do so.

       Compiler  tools will be configured to see the same subset of the store that builds would see. The PATH is
       modified to make all executables in  the  dependency  tree  available  (provided  they  have  been  built
       already).  Commands  are  also  rewritten in the way cabal itself would. For example, `cabal v2-exec ghc`
       will consult the configuration to choose an appropriate version of ghc and to  include  any  ghc-specific
       flags requested.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --builddir, --distdir, --distpref DIR

       cabal v1-configure

       Usage: cabal v1-configure [FLAGS]

       Configure how the package is built by setting package (and other) flags.

       The configuration affects several other commands, including v1-build, v1-test, v1-bench, v1-run, v1-repl.

       The flags --with-PROG and --PROG-option(s) can be used with the following programs:
         alex ar c2hs cpphs doctest gcc ghc ghc-pkg ghcjs ghcjs-pkg greencard haddock
         happy haskell-suite haskell-suite-pkg hmake hpc hsc2hs hscolour jhc ld
         pkg-config runghc strip tar uhc

       Examples:
         cabal v1-configure
           Configure with defaults;
         cabal v1-configure --enable-tests -fcustomflag
           Configure building package including tests,
           with some package-specific flag.

       The v1-configure command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       cabal v1-update

       Usage: cabal v1-update [FLAGS]

       For all known remote repositories, download the package list.

       Relevant global configuration keys:
         remote-repo
         remote-repo-cache
         local-repo

       The v1-update command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       For more information, see: https://wiki.haskell.org/Cabal/NewBuild

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --index-state STATE
                     Update  the  source  package  index  to its state as it existed at a previous time. Accepts
                     unix-timestamps (e.g. '@1474732068'), ISO8601 UTC timestamps (e.g. '2016-09-24T17:47:48Z'),
                     or 'HEAD' (default: 'HEAD').

       cabal v1-build

       Usage: cabal v1-build [FLAGS]
          or: cabal v1-build COMPONENTS [FLAGS]

       Components encompass executables, tests, and benchmarks.

       Affected by configuration options, see `v1-configure`.

       Examples:
         cabal v1-build               All the components in the package
         cabal v1-build foo           A component (i.e. lib, exe, test suite)

       The flags --with-PROG and --PROG-option(s) can be used with the following programs:
         alex ar c2hs cpphs doctest gcc ghc ghc-pkg ghcjs ghcjs-pkg greencard haddock
         happy haskell-suite haskell-suite-pkg hmake hpc hsc2hs hscolour jhc ld
         pkg-config runghc strip tar uhc

       cabal v1-repl

       Usage: cabal v1-repl [COMPONENT] [FLAGS]

       If the current directory contains no package, ignores  COMPONENT  parameters  and  opens  an  interactive
       interpreter session; if a sandbox is present, its package database will be used.

       Otherwise,  (re)configures  with  the given or default flags, and loads the interpreter with the relevant
       modules. For executables, tests and benchmarks,  loads  the  main  module  (and  its  dependencies);  for
       libraries all exposed/other modules.

       The default component is the library itself, or the executable if that is the only component.

       Support  for  loading  specific modules is planned but not implemented yet. For certain scenarios, `cabal
       v1-exec -- ghci :l Foo` may be used instead. Note that `v1-exec` will not (re)configure and you will have
       to specify the location of other modules, if required.

       Examples:
         cabal v1-repl               The first component in the package
         cabal v1-repl foo           A named component (i.e. lib, exe, test suite)
         cabal v1-repl --ghc-options="-lstdc++"  Specifying flags for interpreter

       The v1-repl command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       cabal v1-freeze

       Usage: cabal freeze [FLAGS]

       Calculates a valid set of dependencies and their exact versions. If successful, saves the result  to  the
       file `cabal.config`.

       The package versions specified in `cabal.config` will be used for any future installs.

       An existing `cabal.config` is ignored and overwritten.

       The v1-freeze command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

              --enable-tests
              --disable-tests
                     freezing of the dependencies of any tests suites in the package description file.

              --enable-benchmarks
              --disable-benchmarks
                     freezing of the dependencies of any benchmarks suites in the package description file.

              --solver SOLVER
                     Select dependency solver to use (default: modular). Choices: modular.

              --max-backjumps NUM
                     Maximum number of backjumps allowed while solving (default: 4000). Use a negative number to
                     enable unlimited backtracking. Use 0 to disable backtracking completely.

              --reorder-goals
              --no-reorder-goals
                     Try to reorder goals according to certain heuristics. Slows things down on average, but may
                     make backtracking faster for some packages.

              --count-conflicts
              --no-count-conflicts
                     Try  to  speed  up  solving  by  preferring  goals  that are involved in a lot of conflicts
                     (default).

              --minimize-conflict-set
              --no-minimize-conflict-set
                     When there is no solution, try to improve the error message by finding a  minimal  conflict
                     set (default: false). May increase run time significantly.

              --independent-goals
              --no-independent-goals
                     Treat several goals on the command line as independent. If several goals depend on the same

                     Allow cabal to install base, ghc-prim, integer-simple, integer-gmp, and template-haskell.

              --reject-unconstrained-dependencies none|all
                     Require these packages to have constraints on them if they are  to  be  selected  (default:
                     none).

       cabal v1-haddock

       Usage: cabal v1-haddock [FLAGS]
          or: cabal v1-haddock COMPONENTS [FLAGS]

       Requires the program haddock, version 2.x.

       The v1-haddock command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       cabal v1-install

       Usage: cabal v1-install [FLAGS]
          or: cabal v1-install [FLAGS] PACKAGES

       Installs one or more packages. By default, the installed package will be registered in the user's package
       database or, if a sandbox is present in the current directory, inside the sandbox.

       If  PACKAGES  are specified, downloads and installs those packages. Otherwise, install the package in the
       current directory (and/or its dependencies) (there must  be  exactly  one  .cabal  file  in  the  current
       directory).

       When  using  a  sandbox, the flags for `v1-install` only affect the current command and have no effect on
       future commands. (To achieve that, `v1-configure` must be used.)  In contrast,  without  a  sandbox,  the
       flags to `v1-install` are saved and affect future commands such as `v1-build` and `v1-repl`. See the help
       for `v1-configure` for a list of commands being affected.

       Installed  executables  will  by default (and without a sandbox) be put into `~/.cabal/bin/`. If you want
       installed executable to be available globally, make sure that the PATH environment variable contains that
       directory.  When using a sandbox, executables will be put into `$SANDBOX/bin/`  (by  default:  `./.cabal-
       sandbox/bin/`).

       When specifying --bindir, consider also specifying --datadir; this way the sandbox can be deleted and the
       executable should continue working as long as bindir and datadir are left untouched.

       The flags --with-PROG and --PROG-option(s) can be used with the following programs:
         alex ar c2hs cpphs doctest gcc ghc ghc-pkg ghcjs ghcjs-pkg greencard haddock
         happy haskell-suite haskell-suite-pkg hmake hpc hsc2hs hscolour jhc ld
         pkg-config runghc strip tar uhc

       Examples:
         cabal v1-install                     Package in the current directory
         cabal v1-install foo                 Package from the hackage server
         cabal v1-install foo-1.0             Specific version of a package
         cabal v1-install 'foo < 2'           Constrained package version
         cabal v1-install haddock --bindir=$HOME/hask-bin/ --datadir=$HOME/hask-data/
                                           Change installation destination

       The v1-install command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       cabal v1-run

       Usage: cabal v1-run [FLAGS] [EXECUTABLE] [-- EXECUTABLE_FLAGS]

       Builds  and  then  runs the specified executable. If no executable is specified, but the package contains
       just one executable, that one is built and executed.

       Use `cabal v1-test --show-details=streaming` to run a test-suite and get its full output.

       Examples:
         cabal v1-run
           Run the only executable in the current package;
         cabal v1-run foo -- --fooflag
           Works similar to `./foo --fooflag`.

       The v1-run command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

              --only
                     Don't reinstall add-source dependencies (sandbox-only)

       cabal v1-test

       Usage: cabal v1-test [FLAGS]
          or: cabal v1-test TESTCOMPONENTS [FLAGS]

       If necessary (re)configures with `--enable-tests` flag and builds the test suite.

       Remember that the tests' dependencies must be installed if there are additional ones;  e.g.  with  `cabal
       v1-install --only-dependencies --enable-tests`.

       By  defining  UserHooks  in  a  custom Setup.hs, the package can define actions to be executed before and
       after running tests.

       The v1-test command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       For more information, see: https://wiki.haskell.org/Cabal/NewBuild

       Flags:
              -v, --verbose [n]

       cabal v1-bench

       Usage: cabal v1-bench [FLAGS]
          or: cabal v1-bench BENCHCOMPONENTS [FLAGS]

       If necessary (re)configures with `--enable-benchmarks` flag and builds the benchmarks.

       Remember that the benchmarks' dependencies must be installed if there  are  additional  ones;  e.g.  with
       `cabal v1-install --only-dependencies --enable-benchmarks`.

       By  defining  UserHooks  in  a  custom Setup.hs, the package can define actions to be executed before and
       after running benchmarks.

       The v1-bench command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       cabal v1-exec

       Usage: cabal v1-exec [FLAGS] [--] COMMAND [--] [ARGS]

       A directly invoked GHC will not automatically be aware of any sandboxes: the GHC_PACKAGE_PATH environment
       variable  controls  what  GHC  uses. `cabal v1-exec` can be used to modify this variable: COMMAND will be
       executed in a modified environment and thereby uses the sandbox package database.

       If there is no sandbox, behaves as identity (executing COMMAND).

       Note that other cabal commands change the environment variable appropriately already, so there is no need
       to wrap those in `cabal v1-exec`. But with `cabal v1-exec`, the  user  has  more  control  and  can,  for
       example, execute custom scripts which indirectly execute GHC.

       Note  that  `cabal  v1-repl` is different from `cabal v1-exec -- ghci` as the latter will not forward any
       additional flags being defined in the local package to ghci.

       See `cabal sandbox`.

       Examples:
         cabal v1-exec -- ghci -Wall
           Start a repl session with sandbox packages and all warnings;
         cabal v1-exec gitit -- -f gitit.cnf
           Give gitit access to the sandbox packages, and pass it a flag;
         cabal v1-exec runghc Foo.hs
           Execute runghc on Foo.hs with runghc configured to use the
           sandbox package database (if a sandbox is being used).

       The v1-exec command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

                     The directory where Cabal puts generated build files (default dist)

              -s, --save-configure
                     Do not remove the configuration file (dist/setup-config) during cleaning.   Saves  need  to
                     reconfigure.

       cabal v1-sdist

       Usage: cabal v1-sdist [FLAGS]

       The v1-sdist command is a part of the legacy v1 style of cabal usage.

                     Just write a list of the package's sources to a file

              --snapshot
                     Produce a snapshot source distribution

              --output-directory DIR
                     Generate a source distribution in the given directory, without creating a tarball

       cabal v1-doctest

       Usage: cabal v1-doctest [FLAGS]

       Requires the program doctest, version 0.12.

       The v1-doctest command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you

       cabal v1-copy

       Usage: cabal v1-copy [FLAGS]
          or: cabal v1-copy COMPONENTS [FLAGS]

       Components  encompass  executables  and libraries. Does not call register, and allows a prefix at install
       time. Without the --destdir flag, configure determines location.

       Examples:
         cabal v1-copy               All the components in the package
         cabal v1-copy foo           A component (i.e. lib, exe, test suite) The v1-copy command is  a  part  of

              --global
                     (default)upon registration, register this package in the system-wide package database

              --inplace
                     register the package in the build location, so it can be used without being installed

       cabal v1-reconfigure

       Usage: cabal v1-reconfigure [FLAGS]

       Run  `configure`  with  the  most  recently  used  flags,  or  append  FLAGS  to  the  most recently used
       configuration. Accepts the same flags as `cabal v1-configure'.  If the package has never been configured,
       the default flags are used.

       Examples:
         cabal v1-reconfigure
           Configure with the most recently used flags.
         cabal v1-reconfigure -w PATH
           Reconfigure with the most recently used flags,
           but use the compiler at PATH.

       The v1-reconfigure command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you

       Sandboxes are isolated package databases that can be used to prevent dependency conflicts that arise when
       many different packages are installed in the  same  database  (i.e.  the  user's  database  in  the  home
       directory).

       A  sandbox  in  the  current  directory (created by `v1-sandbox init`) will be used instead of the user's
       database for commands such as `v1-install` and `v1-build`. Note that (a directly invoked)  GHC  will  not
       automatically  be  aware  of  sandboxes;  only  if called via appropriate cabal commands, e.g. `v1-repl`,
       `v1-build`, `v1-exec`.

       Currently, cabal will not search for a sandbox in folders above the current one, so cabal  will  not  see
       the sandbox if you are in a subfolder of a sandbox.

       Subcommands:

       init:
         Initialize a sandbox in the current directory. An existing package database
         will not be modified, but settings (such as the location of the database)
         can be modified this way.

       delete:
         Remove the sandbox; deleting all the packages installed inside.

       add-source:
         Make one or more local packages available in the sandbox. PATHS may be
         relative or absolute. Typical usecase is when you need to make a (temporary)
         modification to a dependency: You download the package into a different
         directory, make the modification, and add that directory to the sandbox with
         `add-source`.

         Unless given `--snapshot`, any add-source'd dependency that was modified
         since the last build will be re-installed automatically.

       delete-source:
         Remove an add-source dependency; however, this will not delete the
         package(s) that have been installed in the sandbox from this dependency. You
         can either unregister the package(s) via `cabal v1-sandbox hc-pkg
         unregister` or re-create the sandbox (`v1-sandbox delete; v1-sandbox init`).

       list-sources:
         List the directories of local packages made available via `cabal v1-sandbox
         add-source`.

       hc-pkg:
         Similar to `ghc-pkg`, but for the sandbox package database. Can be used to
         list specific/all packages that are installed in the sandbox. For
         subcommands, see the help for ghc-pkg. Affected by the compiler version
         specified by `v1-configure`.

       Relevant global configuration keys:
         require-sandbox
         ignore-sandbox

       Examples:
         Set up a sandbox with one local dependency, located at ../foo:
           cabal v1-sandbox init
           cabal v1-sandbox add-source ../foo
           cabal v1-install --only-dependencies
         Reset the sandbox:
           cabal v1-sandbox delete
           cabal v1-sandbox init
           cabal v1-install --only-dependencies
         List the packages in the sandbox:
           cabal v1-sandbox hc-pkg list
         Unregister the `broken` package from the sandbox:
           cabal v1-sandbox hc-pkg -- --force unregister broken

       The v1-sandbox command is a part of the legacy v1 style of cabal usage.

       It is a legacy feature and will be removed in a future release of cabal-install. Please file a bug if you
       cannot replicate a working v1- use case with the new-style commands.

       Flags:
              -v, --verbose [n]
                     Control verbosity (n is 0--3, default verbosity level is 1)

              --snapshot
                     Take a snapshot instead of creating a link (only applies to 'add-source')

              --sandbox DIR
                     Sandbox location (default: './.cabal-sandbox').
