Offer to help development: Convert MIDI to Lilypond

[Joseph Austin]

Lilypond Developers:

I am offering to help with the project of converting midi2ly from C to Python, 
or more generally converting MIDI to Lilypond.

Per attached, I understand an initial conversion attempt has been started and 
is awaiting completion and testing.

I'm not sure if this is a good place for someone new to Lilypond internals to 
start,
but it seems this should be a relatively independent utility so I shouldn't 
need a significant background in the internals.

I may need a "mentor" to help get started with the nuts and bolts of Lilypond 
development.  

I've done programming for a living in C++, Java, PHP, and a few others, but not 
Python [too new] or C [too old],
though I am somewhat familiar with both, and also somewhat familiar with the 
structure of MIDI.
