+ (description
+ "This library provides generic parsers for parsing S-expressions from
+strings or other medium.
+
+The library is focused on performances but still provide full generic
+parsers that can be used with strings, bigstrings, lexing buffers,
+character streams or any other sources effortlessly.
+
+It provides three different class of parsers:
+@itemize
+@item
+the normal parsers, producing [Sexp.t] or [Sexp.t list] values
+@item
+the parsers with positions, building compact position sequences so
+that one can recover original positions in order to report properly
+located errors at little cost
+@item
+the Concrete Syntax Tree parsers, produce values of type
+[Parsexp.Cst.t] which record the concrete layout of the s-expression
+syntax, including comments
+@end itemize
+
+This library is portable and doesn't provide IO functions. To read
+s-expressions from files or other external sources, you should use
+parsexp_io.")
