I think the idea here is to allow something like
pip install scipy
but for non-packages - so you can find where dials_regression etc. are when you do a fresh build, without having to remember where to git clone everything from
if I pip install something I do not need to know where the bytes come from - same idea - and real world here is defined as “the usual way things work in Python”
Warehouse is effectively a directory…
For us in dials land this is very helpful as things come from all over the place
Obviously the use of this is *optional* and you can just remember the URL’s if you want…
Cheers Graeme

Just out of curiosity: what's your definition of "real world"?

commit 914c74bf195b5e5d4fa2c4145da3e5f89c7e5872
Author: Markus Gerstel mailto:[email protected]
Date: Tue Mar 13 10:43:22 2018 +0000
New command: libtbx.install
This downloads and configures from a select list of cctbx/libtbxish
modules in a similar manner to pip in the real world. This will not
update or install any libraries in the base build, but assuming
those libraries are present libtbx.install should work.
