+    (description
+     "The original WEB system by Donald Knuth has the macros webmac.tex that
+produce DVI output only; for historic reasons, it will never be
+modified (apart from catastrophic errors).  Han The Thanh has modified these
+macros in his @file{pdfwebmac.tex} for PDF output (only) with pdfTeX.
+Jonathan Kew's XeTeX has similar macros @file{xewebmac.tex} by Khaled Hosny
+that modify @file{webmac.tex} for PDF output; these macros can only be used
+with a specific TeX engine each.  The present @code{pwebmac} package
+integrates these three WEB macro files similar to @file{cwebmac.tex} in Silvio
+Levy's and Don Knuth's CWEB system, so @file{pwebmac.tex} can be used with
+Plain TeX, pdfTeX, and XeTeX alike.
+
+Its initial application is the production of PDF and HINT files for all major
+WEB programs for TeX and friends.  For this purpose, the shell script
+@command{makeall} was whipped together; it provides various command line
+options and works around several quirks in the WEB sources.
+
+WEB programmers who want to use @file{pwebmac.tex} instead of the default
+@file{webmac.tex} in their programs have to change the first line in the TeX
+file created by @code{weave}.  From there, all depends on the TeX engine you
+use.")
