\def\name{\tt POOLtype}

\N0\*. About \namegpc.\fi

This is an adaption of Donald~E. Knuth's \.{POOLtype}, version 3
from September 1989, to Unix. It is based on GNU~Pascal, version 2.1.

This program expects the input file (\.{.pool}) file,
which is a pool file, on the command line.  To support shell
scripting, \namegpc\ sets the exit code to one when something was
wrong with the input file.

\hint

Comments and questions are welcome!
