I agree, I like this one. (Of course, Pete and I colluded and came up
with it before he sent the mail. But still, I like it. :)

i would argue against the term 'framework'. parsely really is a back-end,
meaning it can be called separately from your configuration tool, and
it really doesn't dictate any of the structure of your tool. (is this

i like the addition of the word 'files' here. it makes it much cleaner.

I don't think that saying python/pcre/spark is gratuitous. mind you, i
have no idea what pcre and spark are until i see the c/flex/bison comment,
and then i know that pcre is a flex lookalike and spark is a bison
lookalike. (am i right? (maybe i mean workalike rather than lookalike. but
you get the picture.)) i think this is fine.

Parsely is designed to be able to easily understand new configuration
formats. It generates a parse tree from the configuration files, which
a program such as foo or bar (Linuxconf?) can use to conveniently modify
and store back the values. Parsely is organized to support a wide variety
of languages, scanners, and parsers, and adding support for new ones is
i might consider putting this paragraph in the middle, since it leads
nicely into the how far along am i paragraph.

i should sleep rather than addressing the longer announcement now.
but it looks good overall.
