       gencmn - generate an ICU memory-mappable data file

       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 ]

       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.

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

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

              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 des-
              tination directory is  specified  by  the  environment  variable

       -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

       ICU_DATA  Specifies the directory  containing  ICU  data.  Defaults  to
                 ${prefix}/share/icu/69.1/.   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.
