[IronPython] Exception Model for modules implemented in C#

[Dino Viehland]

There's this: http://www.mail-archive.com/users@lists.ironpython.com/msg10503.html

That originally came from the .rst files used to generate docs (External.LCA_RESTRICTED\Languages\IronPython\27\Doc\IronPythonDocs) but I can't find it in there now...  I'm not quite sure how that happened.

Thanks, I think that will help out a lot!

I don't think there is. It's not too bad once you figure it out, but
figuring it out is tricky, to say the least.

You could look at
https://bitbucket.org/jdhardy/ironpython.sqlite/src/95894443fffe/src/Exceptions.cs,
which has it all in one place for a fairly deep exception hierarchy.
(`InitModuleExceptions` is called from `PerformModuleReload` in
_sqlite.cs.) I just figured that out from reading the existing
modules, but I'm thinking I should write a "module implementer's
guide" with those sorts of lore in it. I thought there was one
started, but now I can't find it.
