+     "PerlTeX is a combination Perl script (@file{perltex.pl}) and LaTeX2e
+package (@file{perltex.sty}) that, together, give the user the ability to
+define LaTeX macros in terms of Perl code.  Once defined, a Perl macro becomes
+indistinguishable from any other LaTeX macro.  PerlTeX thereby combines
+LaTeX's typesetting power with Perl's programmability.  PerlTeX will make use
+of persistent named pipes, and thereby run more efficiently.  Also provided is
+a switch to generate a PerlTeX-free, document-specific, @file{noperltex.sty}
+that is useful when distributing a document to places where PerlTeX is not
+available.")
