The occam parser is now a GenParser Token OccState, rather than a GenParser
Char OccState, and a lot of now-redundant code has been removed. The parser is
also somewhat faster, which wasn't intended but is nice anyway.
I've also modified the Rain parser to not rely on the old preprocessing code;
it wasn't appropriate for Rain's syntax anyway, so I assume Neil will be
replacing it eventually.
It turns out there's a Prelude function that does what readSource does already
-- so just use that. (I was in the process of moving readSource into Utils when
I found it, since I want to use it in other places.)
The compiler itself is under the GPLv2+; the support code that gets built into
user programs is under the LGPLv2+. This matches the existing practice for the
KRoC project.
(As with Occade, I've used the new GPLv3-style license header in the source
files, though, since that avoids having to update the FSF's postal address.)
