 It may also be worth adding support for parsing the files under .egg-info
- for instance, those 'extras' in requires.txt.
 See the 'requires()' method of Distribution objects:
 http://peak.telecommunity.com/DevCenter/PkgResources#distribution-methods
 
I've already looked into that before (in pkg_resources.py) - unfortunately, 
this does not return all of requires.txt (as Python dict, that is), but only 
*what* you specify in the 'extras' argument (how am I supposed to know the /
possible/ extras sections beforehand?).
 
The closest I've come to is using `split_sections` and `_get_metadata` to 
construct the dict myself. But that is not the ideal way to provide/use an API.
 

PJE: Ah, you didn't say that, you just said "parse".  If you'll file a feature 
request, I'll replace _dep_map with a public attribute for accessing that 
information in a future release.  In the meantime, you're quite safe 
using ._dep_map, since obviously I'm not going to change it out from under 
you.
