flf2a$ 5 4 20 0 16
Font : Dr. Pepper (after a name in one sig done in this style).
Author: Eero Tamminen, t150315@cc.tut.fi.
Characters '#' and '&' are lousy and I'm not very satisfied
with the '$' or 't'... Suggestions?
Explanation of first line:
flf2 - "magic number" for file identifiction
a - should always be `a', for now
$ - the "hardblank" -- prints s a blank, but can't be smushed
5 - height of a character
4 - height of a character, not including descenders
20 - max line length (excluding comment lines) + fudge factor
0 - default smushmode for this font
16 - number of comment lines
