The first PLtoTF program was designed by Leo Guibas in the summer of 1978. Contributions by Frank
Liang, Doug Wyatt, and Lyle Ramshaw also had a significant effect on the evolution of the present
code.
Extensions for an enhanced ligature mechanism were added by D.E. Knuth in 1989.
Extensions to handle extended font metric files (``OFM'') were added by John Plaice in December
1995 and January 1996, resulting in the new program OPL2OFM.
