NAME

       gencmn - generate an ICU memory-mappable data file

SYNOPSIS

       gencmn  [  -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright | -C, --comment comment ] [ -d, --destdir
       destination ] [ -n, --name name ] [ -t, --type fileext ] [ -S, --source  ]  [  -e,  --entrypoint  name  ]
       maxsize [ listfilename ]

DESCRIPTION

       gencmn  takes  a  set  of files and packages them as an ICU memory-mappable data file. The resulting data
       file can then be used directly by ICU.

       gencmn reads a list of files to be packaged from either the  supplied  listfilename  file,  or  from  its
       standard  output.  It packages all the files from the list that are not bigger than maxsize bytes, except
       if maxsize is 0, which indicates that there is no size limit on files.

OPTIONS

       -h, -?, --help
              Print help about usage and exit.

       -v, --verbose
              Display extra informative messages during execution.

       -c,--copyright
              Include the ICU copyright notice in the resulting data.

       -C, --comment comment
              Include the specified comment in the resulting data instead of the ICU copyright notice.

       -d, --destdir destination
              Set the destination directory to destination.  The default destination directory is  specified  by
              the environment variable ICU_DATA.

       -n, --name name
              Set  the  data name to name instead of the default. This name is also used as the base name of the
              output. The default name is made of the icudt prefix,  followed  by  a  two-digit  version  number
              corresponding  to  the  current  version  of  the  ICU release, and a single letter indicating the
              endianness of the data (the letter b indicated big endian data, and the letter l indicates  little
              endian ones).

       -t, --type type
              Use  type  as  the type of the data. This type is also used as the extension of the generated data
              file. The default type ie dat.

       -S, --source
              Write a C source file with the table of contents of the data.

       -e, --entrypoint name
              Set the data entry point (used for linking against the data in a shared  library  form)  to  name.
              The  default  entry  point  name is made of the data (set by the -n, --name option) followed by an
              underscore and the type of the data (set by the -t, --type option).

ENVIRONMENT

       ICU_DATA  Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/76.1/.  Some tools
                 in ICU depend on the presence of the trailing slash. It is thus important to make sure that  it
                 is present if ICU_DATA is set.

VERSION
