\N0\*. About \namefpc.\fi
This is an adaption of Donald~E. Knuth's \.{TFtoPL}, to Unix.
\namefpc\ is based on the Free~Pascal Compiler.

\namefpc\ expects the name of the input file (\.{.pl}) as the first
and the name of the output file (\.{.tf}) as the second parameter
on the command line.

\hint

Comments and questions are welcome!
