would a note in the pants repo about how to edit

build-suppport/pants_venv

to add

-f

to the pip install line to use a development/from-source version of any of pants's dependencies be useful? where would that note be most useful to add?

Yes! I think the how to develop file

Also the venv should live elsewhere, since we have checked-in files under

build-support

, and it's confusing to also have generated files there.
