NAME

       cpangraph - Generate dependency chain graphs for CPAN modules

VERSION

       Version 0.12

SYNOPSIS

         cpangraph [options] <file>

           Options:
             --help            display a brief help message
             --perl=VERSION    filter those available in Perl core
             --phase=PHASE     filter those needed for a phase (e.g., build)
             --rankdir         controls the GraphViz 'rankdir' variable
             --reverse         graph reverse dependencies (dependents)
             --verbose         display additional debugging information

OPTIONS

       --help
           Prints a brief help message to the standard output and exits.

       --perl=VERSION
           This  displays  dependencies  which have been available in Perl core since the given VERSION. It does
           not currently know if a module has been removed from  core,  but  this  is  an  unlikely  occurrence.
           Specify Perl versions in the form:

             5.008008 # for versions >= 5.8.8
             5.010    # for versions >= 5.10

       --phase=PHASE
           This  displays dependencies which are needed for a given module's install or runtime PHASE. Available
           phases are:

           •   runtime: required whenever the module is used

           •   build: required to build the module

           •   configure: these are required while preparing the module for build

       --rankdir
           In GraphViz, the 'rankdir' attribute controls the direction that the nodes are  linked  together.  If
           set, the graph will use left -> right linking of nodes rather than the default up-down linking.

       --reverse
           Create  a  graph  of  the  reverse  dependencies  of  a  package (the packages which depend on it, or
           dependent packages).

       --verbose
           Display extra output useful during debugging.

DESCRIPTION

       This script will use the CPAN  Database  to  build  a  graph  of  a  package's  dependencies  or  reverse
       dependencies (dependent packages).
