-.SH DESCRIPTION
-.B gentz
-reads a
-.I timezone
-file and compile it into a binary form.
-The resulting file,

-.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 .
-.SH ENVIRONMENT
-.TP 10
-.B ICU_DATA
-Specifies the directory containing ICU data. Defaults to
-.BR @thepkgicudatadir@/@PACKAGE@/@VERSION@/ .
-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.
-.SH FILES
-The following file is read by
