+     "EmPy is a system for embedding Python expressions and statements in
+template text; it takes an EmPy source file, processes it, and produces
+output.  This is accomplished via expansions, which are special signals to the
+EmPy system and are set off by a special prefix (by default the at sign, @).
+EmPy can expand arbitrary Python expressions and statements in this way, as
+well as a variety of special forms.  Textual data not explicitly delimited in
+this way is sent unaffected to the output, allowing Python to be used in
+effect as a markup language.  Also supported are callbacks via hooks,
+recording and playback via diversions, and dynamic, chainable filters.  The
+system is highly configurable via command line options and embedded
+commands.")
