+ SHORT="Happy is a parser generator for Haskell"
+cat << EOF
+Happy is a parser generator system for Haskell, similar to the tool `yacc'
+for C. Like `yacc', it takes a file containing an annotated BNF specification
+of a grammar and produces a Haskell module containing a parser for the grammar.
+
+Happy is flexible: you can have several Happy parsers in the same program,
+and several entry points to a single grammar. Happy can work in conjunction
+with a lexical analyser supplied by the user (either hand-written or generated
+by another program), or it can parse a stream of characters directly (but
+this isn't practical in most cases).
+
+As of version 1.5, Happy is capable of parsing full Haskell. We have a
+Haskell parser that uses Happy, which will shortly be part of the library
+collection distributed with GHC.
