So... what is the 'standard' or 'best practice' way to work with #python virtual environments and dependencies these days?

It should work on all platforms (aka linux/osx/win) as I want to introduce it into our projects so that all devs can easily start off from the same base, as in a single command to set up env+deps
(as opposed to everyone having to go through the pain individually for each project).

Any pointers or good blog posts that I can peruse?
