He he,

I learned that you can merge multiple times the same branch...
I guess I will merge this quickly any objection?

Olivier

PS: I will auto-review the change ;-)

There seem to be *a lot* of modifications which are however probably just some re-structuring an reshuffling of the various bits of HEPToolsInstaller.py.
Would you mind describing a bit your changes? Thanks!

[Olivier Mattelaer (olivier-mattelaer)]

Note that revision 109 change a lot but at the same time,
it actually is mainly identation and adding
if "__main__" == __name__
at couple of place.
The reason is that I want to be able to do
import HEPToolsInstaller
and not run the code.
So this is in principle harmless.

[Valentin Hirschi (valentin-hirschi)]

Ok, that's a very positive change. I like the idea of being able to use this tool both as a standalone and a python module. Thanks.
