   5 # glyph comment colorizing
   6 # (c)2004 Stepan Roh (PUBLIC DOMAIN)
   7 # usage: ./colorize.pl color sfd_files+ < glyph_codes_file
   8 #  will create files with suffix .color
   9 #  color is either none, yellow, green or hexadecimal 24bit value (0xff0000 is red)
  10 #  glyph_codes_file should contain codes of glyphs to be colored delimited by whitespace and/or commas
  11 #  - glyph codes are U+nnnn (nnnn is hexadecimal)
  12 #  - syntax for code ranges: U+nnnn-U+nnnn (no whitespace inside)
  13 #  file colorize.pe is created during the execution (it is safe to remove it after)
  14
  15 # change to the fontforge binary location if it is not in the system PATH
