+ (description
+ "Parseq (pronounced parsec) is a parsing library for common lisp. It can
+be used for parsing lisp's sequences types: strings, vectors (e.g. binary
+data) and lists. Furthermore, parseq is able to parse nested structures such
+as trees (e.g. lists of lists, lists of vectors, vectors of strings).
+
+Parseq uses parsing expression grammars (PEG) that can be defined through a
+simple interface. Extensions to the standard parsing expressions are
+available. Parsing expressions can be parameterised and made context
+aware. Additionally, the definition of each parsing expression allows the
+arbitrary transformation of the parsing tree.
+
+The library is inspired by Esrap and uses a very similar interface. No code
+is shared between the two projects, however. The features of Esrap are are
+mostly included in parseq and complemented with additional, orthogonal
+features. Any resemblance to esrap-liquid is merely coincidental.")
