ttf2pfb is oriented towards support for CJK fonts containing several
thousand glyphs to be splitted into subfonts with 256 characters each usable
by TeX. Nevertheless, it is quite generic and works with normal ttf files
too.

Some features are still missing or should be added for convenience:

. Documentation. ttf2pbf explains itself; t1asm is a filter which converts
  the (disassembled) pseudo font created by ttf2pfb into a real PFA font
  (or PFB if you use the `-b' command line switch).

  Example for an ordinary font:

    ttf2pfb -v -m -enc Uni-T1.enc -f FooBar -o foobar.ps foobar.ttf
    t1asm -b < foobar.ps > foobar.pfb
    printafm foobar.pfb > foobar.afm
    afm2tfm foobar.afm

  Example for a CJK font in Big 5 encoding to be used with the CJK package
  for LaTeX (note that the call creates just the first subfont):

    ttf2pfb -c -pid 3 -eid 4 -plane 1 -f FooBar01 -o foobar01.ps foobar.ttf
    t1asm -b < foobar01.ps > foobar01.pfb
    printafm foobar01.pfb > foobar01.afm
    afm2tfm foobar01.afm

. Inclusion of t1asm and t1binary into ttf2pfb so that ttf2pfb can directly
  produce PFA and PFB files.

. Overlapping outlines produce incorrect shapes: The overlapping areas
  appear white instead of black.

. A more flexible encoding file format (maybe similar to ttf2tfm) which can
  handle glyph names.

. [t1asm has been slightly patched to allow partial font downloading with
  dvips.]

. Note that compiling ttf2pfb with `-O2' doesn't work, most probably due to
  a compiler bug (we've tested with gcc 2.7.2.1 and 2.7.2.3).
