Please see
http://svn.python.org/projects/sandbox/trunk/setuptools/doc/formats.txt for
source, or http://peak.telecommunity.com/DevCenter/EggFormats for an
HTML-formatted version.
Included are summary descriptions of the formats of all of the standard
metadata produced by setuptools, along with pointers to the existing
manuals that describe the syntax used for representing requirements, entry
points, etc. as text. The .egg, .egg-info, and .egg-link formats and
layouts are also specified, along with the filename syntax used to embed
project/version/Python version/platform metadata. Last, but not least,
there are detailed explanations of how resources (such as C extensions) are
extracted on-the-fly and cached, how C extensions get imported from
zipfiles, and how EasyInstall works around the limitations of Python's
default sys.path initialization.
If there's anything else you'd like in there, please let me know.
