   6 # This script is an assistant for printing rules for pasting into
   7 # *.rules files.  The idea is that you get bdfs of the font you don't
   8 # and do like, and specify the character, and it will print a rule
   9 # that fixes it.
  10 #
  11 # Final argument, if 1, says the glyph is a letter without an
  12 # ascender, and edits the regexp not to match the whitespace where
  13 # accents might go.
