Right.  The basic idea is when you have a script that uses Python, but
which consists of more text than Python code.

Command line parameters are a possibility, although you could pass them
in with bindings through the command line -E facility:

	em.py -E 'args = [1, 2, "hello"]' yourscript.em

I'm not sure what ramifications being able to pass command line
arguments in would have, or even what they would look like (since
multiple empy files can be specified on the command line).

Yes, that's a good idea; it needs more examples.  I'm still in the
process of converting my (many) sites which used m4 for the same purpose
to empy.  Here's a description of the process I use for my Web sites
(although still in m4 for some):

The later projects use Python instead of Perl for the cataloguing
process, build databases, and then prepare include files for m4 ... at
which point, the obvious question became, "Why don't I just do this all
in Python -- cataloguing, database building, and then template
processing?"  That's how empy was born.  (That's also why empy supports
m4-style diversions ...)

Thanks for your comments.
