5 """Generate binary message catalog from textual translation description.
6
7 This program converts a textual Uniforum-style message catalog (.po file) into
8 a binary GNU catalog (.mo file). This is essentially the same function as the
9 GNU msgfmt program, however, it is a simpler implementation.
10
11 Usage: msgfmt.py [OPTIONS] filename.po
12
13 Options:
14 -o file
15 --output-file=file
16 Specify the output file to write to. If omitted, output will go to a
17 file named filename.mo (based off the input file name).
18
19 -h
20 --help
21 Print this message and exit.
22
23 -V
24 --version
25 Display version information and exit.
26
27 -s
28 --statistics
29 Display fuzzy and untranslated counts
