.SH DESCRIPTION
.B 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.
.PP
.B gencmn
reads a list of files to be packaged from either the
supplied
.I listfilename
file, or from its standard output. It packages all the files from
the list that are not bigger than
.I maxsize
bytes, except if
.I maxsize
is 0, which indicates that there is no size limit on files.
.SH OPTIONS
.TP
.BR "\-h\fP, \fB\-?\fP, \fB\-\-help"
Print help about usage and exit.
.TP
.BR "\-v\fP, \fB\-\-verbose"
Display extra informative messages during execution.
.TP
.BR \-c\fP, \fB\-\-copyright
Include the ICU copyright notice in the resulting data.
.TP
.BI "\-C\fP, \fB\-\-comment" " comment"
Include the specified
.I comment
in the resulting data instead of the ICU copyright notice. 
.TP
.BI "\-d\fP, \fB\-\-destdir" " destination"
Set the destination directory to
.IR destination .
The default destination directory is specified by the environment variable
.BR ICU_DATA .
.TP
.BI "\-n\fP, \fB\-\-name" " name"
Set the data name to
.I name
instead of the default. This name is also used as the base name of the
output. The default name is made of the
.I 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
.I b
indicated big endian data, and the letter
.I l
indicates little endian ones).
.TP
.BI "\-t\fP, \fB\-\-type" " type"
Use
.I type
as the type of the data. This type is also used as the extension of
the generated data file. The default type ie
.IR dat .
.TP
.BI "\-S\fP, \fB\-\-source"
Write a C source file with the table of contents of the data.
.TP
.BI "\-e\fP, \fB\-\-entrypoint" " name"
Set the data entry point (used for linking against the data in a
shared library form) to
.IR name .
The default entry point name is made of the data (set by the
.BI "\-n\fP, \fB\-\-name"
option) followed by an underscore and the type of the data (set by the
.BI "\-t\fP, \fB\-\-type"
option).
.SH ENVIRONMENT
.TP 10
.B ICU_DATA
Specifies the directory containing ICU data. Defaults to
.BR ${prefix}/share/icu/73.1/ .
Some tools in ICU depend on the presence of the trailing slash. It is thus
important to make sure that it is present if
.B ICU_DATA
is set.
