Internal Program Version: t1utils  1.39

The t1utils are a collection of simple type-1 font manipulation programs.
Together, they allow you to convert between PFA (ASCII) and PFB
(binary) formats, disassemble PFA or PFB files into human-readable
form, and reassemble them into PFA or PFB format. Additionally, you can
extract font resources from a Macintosh font file (ATM/Laserwriter) or
create a Macintosh Type 1 font file from a PFA or PFB font.
