      1 # Convenient makefile for managing translations.

      3 # Prerequisites:
      4 # - GNU gettext
      5 # - Python
      6 
      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.
