Moderate changes and improvements; please review and, if appropriate, merge.

I release my changes under the same permissive license as specified in the LICENSE file, and you may feel free to incorporate them while attributing the copyright to yourself.

JSYK, I am also looking at generalizing this, to support a .env file or .env/ directory inside $VIRTUAL_ENV/.  If I do that and you don't otherwise object, I will attribute the copyright on that project to myself, and list your two projects as inspiration.  This is in case I want to standardize on releasing my projects under a different permissive license.
