So let me explain... they are something like 5k files, each one with
some 5k code lines. Anyway (and furthermore) by my team requirement,
any optimization, even in development/coding level, even in run-time
level, cannot be done with any creation of new files of folders. I can
use gnat prepost as well, but what we already have been doing is a
prep, so the number of steps doing this would be the same, and it does
not worth doing. What I wanted is to change some directives in the
code (which I could make a bash script for doing this easily) which
already are there, but now relate them to scenarios watches, and as I
choose Scenario "Thing" and make compile/build, GPS can identify
automatically...'this part of code do not belong to this scenario
"Thing", so I should not compile/build it with the whole project', and
just ignore it: the idea is as we were hiding the prep phase, but the
text codes do not change actually.
