Developers may not provide their own "METADATA" file. The "sdist"
command will, if it detects an existing "METADATA" file, terminate
with an appropriate error message. This should prevent confusion
caused by the "METADATA" and "setup.py" files being out of sync.

RFC822 is an interesting choice. I was initially thinking XML, but I kind
of like the RFC822 idea. Probably good to note above that multi-line
entries must have white-space at the beginning of their continued lines...

Questions: Is it expected this name corresponds either to the name of the
package which is imported, or the package top-level directory name? If so,
what do we do about alternative packages that provide different implementations
of the same functionality? I suppose we could reasonably expect to make
use of "import urllib2 as urllib" to take care of that.
Proposed valid characters: [-a-zA-Z_0-9]

See my other message about "Description" versus "Short-Description" and
Group (such as "Database", "Network/SMTP", etc)?
Provides (maybe "urllib2" would provide "urllib"?)
Requires (dependences -- RPM for example has multiple lines of the
form "Requires: initscripts >= 3.25", "Requires: openssl >= 0.9.4")
In general, it looks good.
There is no force so powerful as an idea whose time has come.
