\%[\fIinput\fR [\fIoutput\fR]]
.SH DESCRIPTION
.B t1disasm
disassembles Adobe Type 1 font programs in either PFA (hexadecimal) or PFB
(binary) formats into human-readable form. If the file
.I output
is not specified output goes to the standard output.
If the file
.I input
is not specified input comes from the standard input.

.B t1disasm
performs eexec and charstring decryption as specified in the ``black

Additionally, the charstring binary tokens are expanded into human-readable
text form, using the names given in the black book and later documents
describing Type 2 opcodes.
