+"""Generate binary message catalog from textual translation description.
+
+This program converts a textual Uniforum-style message catalog (.po file) into
+a binary GNU catalog (.mo file). This is essentially the same function as the
+GNU msgfmt program, however, it is a simpler implementation.
+
+Usage: msgfmt.py [OPTIONS] filename.po
+
+Options:
+ -o file
+ --output-file=file
+ Specify the output file to write to. If omitted, output will go to a
+ file named filename.mo (based off the input file name).
+
+ -h
+ --help
+ Print this message and exit.
+
+ -V
+ --version
+ Display version information and exit.
