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/74.2/.  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.
