+This module is an extension to the Math::Symbolic module. A basic
+familiarity with that module is required.
+
+The Math::Symbolic::Custom::Pattern module implements pattern matching
+routines on Math::Symbolic trees. The patterns itself are constructed from
+Math::Symbolic trees with just a few variables which have a special
+meaning.
+
+The module provides two interfaces. You can use the new() and match()
+methods this class provides, or you can use the to_pattern() and
+is_of_form() methods on any Math::Symbolic tree. (Exported by the
+Math::Symbolic::Custom::Pattern::Export module. Refer to that module for
+details on is_of_form().)
