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
