.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"
|
|

.BI "\-d\fP, \fB\-\-destdir" " destination"
|
|
Set the destination directory to
|

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
|

|
|
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).

.B ICU_DATA
|
|
Specifies the directory containing ICU data. Defaults to

|
important to make sure that it is present if

|
|
is set.
