Use entrypoint.dist.get_metadata('PKG-INFO') to get the PKG-INFO file
as a string. See the PKG-INFO format PEPs to understand what's in there.
Use entrypoint.dist.version to get the version, without needing to
parse PKG-INFO. (Well, it may get parsed for you, if it's a
"develop" egg. But the point is, you don't need to explicitly mess
with PKG-INFO unless you want to get other data than the version.)

You don't need to instantiate those metadata classes; that's done for
you automatically by functions like 'find_distributions()'. The
entrypoint.dist attribute will give you a distribution with the right
type of metadata already attached. Likewise, distribution objects
obtained from a WorkingSet or Environment will be properly initialized as well.
