I haven't been able to do so, is it possible ?

I'm trying to make an org file that will take care of fetching and
intsalling all my required packages, and it would really help in making
things more streamlined, if shell blocks could source some variables from
'accessible' places in the file...

It would be even more convenient if I could use :PROPERTIES: drawers, but I
wasn't even able to do that in a language other than elisp, so I'm not
holding my breath here.

Any help will be appreciated though !

Regards, fellow org-moders.
