     "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.")
