+
+> Hi,
+> 
+> The font mustly large, especially traditional chinese font more then 13 MB.
+> 
+> I used python and fontforge to take PO file's msgstr, and generate a subset font file.
+> here is the files:
+>   - python script:
+>     http://www.ossacc.org/Members/song/DrWangFreeTTF/maketuxfont.py
+>   - fontforge script: 
+>     http://www.ossacc.org/Members/song/DrWangFreeTTF/tuxpaintsubset.pe
+>   - the traditional chinese font subset file:
+>     http://www.ossacc.org/Members/song/DrWangFreeTTF/zh_tw.ttf
+> 
+> Usage: (put the scripts together)
+> 
+>  $ ./maketuxfont.py -h
+>   usage: ./maketuxfont.py [options] original_font_file
+> 
+>   options:
+>     --version   show program's version number and exit
+>     -h, --help  show this help message and exit
+>     -lLOCALE, --locale=LOCALE
+>                 to make the locale fonts subset
+>     -pPOFILE, --pofile=POFILE
+>                 parse the pofile to get strings
+> 
+> Example:
+> 
+>  $ ./maketuxfont.py \
+>     -l zh_tw \
+>     -p tuxpaint/src/po/zh_tw.po \
+>     -p tuxpaint-stamps/po/tuxpaint-stamps-zh_tw.po \
+>     wp010-05.ttf
+> 
+> then will get the "zh_tw.ttf"  file.
