+ (description
+ "PackCC is a packrat parser generator for the C programming language.
+Its main features are:
+@itemize
+@item Generates a parser in C from a grammar described in a PEG.
+@item Gives your parser great efficiency by packrat parsing.
+@item Supports direct and indirect left-recursive grammar rules.
+@end itemize
+The grammar of your parser can be described in a @acronym{PEG, Parsing
+Expression Grammar}. The PEG is a top-down parsing language, and is similar
+to the regular-expression grammar. The PEG does not require tokenization to
+be a separate step, and tokenization rules can be written in the same way as
+any other grammar rules.")
