The hardest part of reading the file formats is pinning them down.
Larry Fish was very helpful in resolving minor ambiguities in the
Compass file format descriptions, which was very useful when writing
the Survex support for Compass formats.
Without a precise spec or a lot of sample data from a range of sources,
you're likely to end up handling just a subset of the format.
But generally it's going to be easier for processed data formats than
unprocessed data formats as they're written by machines, so the
format-as-defined-by-use has a lot less variation, even if you don't
have a formal specification.

You get compass "for free" with the Survex "img" library - it
transparently reads .plt files (and processed CMAP files).
