Bg5pdf is a simple wrapper for wrapping big5 encoding text file into PDF file by using PDFlib. The output of this program does not contain embedded fonts. You have to download the Acrobat Acroread Asianfont pack to view and print the output file or use TrueType fonts with Xpdf. This wrapper does not provide any formatting functions except simple line wrapping. If you need sophisticated formatting, you should try CJK-LaTex or other equivalent tools. The Python script "bg5pdf" is released under the Gnu Public License. bg5pdflib.c and bg5pdflib.so are released under the Aladdin Free Public License, because the work is based on PDFlib.
