1# Convenient makefile for managing translations.

3# Prerequisites:
4# - GNU gettext
5# - Python

7# Adding new translations
8# -----------------------
9
10# To start working on a new translation edit the POS=... line
11# below. If you want to add for example a french translation, add
12# fr.po.
13
14# Then run "make po" to generate a fresh .po file from translatable
15# strings in t_options.h. Now you can edit the new .po file (fr.po in
16# the example above) to translate the strings. Please make sure that
17# your editor encodes the file in UTF-8.
18
19# Updating existing translations
20# ------------------------------
21
22# Run "make po" to update .po files with new translatable strings from
23# t_options.h. Now you can edit the .po files you're interested
24# in. Please make sure that your editor encodes the file in UTF-8.
25
26# Updating options.h
27# ------------------
28
29# Finally run "make" to generate options.h from t_options.h with all
30# translations. Now you can rebuild the drivers. Any common options
31# used by the drivers will have option descriptions with the latest
32# translations.
33
34# Publishing translations
35# -----------------------
36
37# To get your translation(s) into Mesa CVS, please send me your
38# <lang>.po file.
