"""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.
