NOTE: this is not really a readme, it is notes, a readme for me.
Perhaps a "readyou" or something. For usage, see USAGE instead.
===============================================================

Create simple config file parser as described in the TODO
for mmss.

Should use maybe sed or awk. Or maybe even just write it with
flex?? It shouldn't be remotely difficult... OK, string handling
in C can be dodgy. Perhaps use some string library for sanity's
sake.

Ah, wait. Considering the keys could be anything, and there's
next-to-no structure, regexps would be a squillion times better.

Yep. Done it, or at least most of it, now, using the PCRE library.
Not all operations are supported, and comments aren't properly
ignored -LIST ignores them, but ops that take keys need to first
check the key against a first regexp to check it's a valid one.
Alternatively, we could just check the first char isn't a #, and
check directly what the other chars are without a regexp.

I think whitespaces should be illegal in keys (not values though).
Don't know if there's some way newlines can be placed in values
without screwing up the fact this is a line-oriented format.

Keys should probably be limited to alphanumerics, and the symbols
_./-~,+   ...I think that should be enough, allows for versatile
uses...
