</p><p>The <code>.cabal</code> file format is not trivial, especially with the introduction
of configurations and the section syntax that goes with that. This module
has a bunch of parsing functions that is used by the <code>.cabal</code> parser and a
couple others. It has the parsing framework code and also little parsers for
many of the formats we get in various <code>.cabal</code> file fields, like module
names, comma separated lists etc.
