3 Example for font handling
5 This tool dumps font information into C files
6 which can be included to rfxswf applications.
7 This is an easy way for developers to use
8 fonts in applications without dealing with
11 Usage: ./dumpfont filename.swf > myfont.c
13 Limits: does not parse ST_DEFINEFONT2
15 Part of the swftools package.
