preflight.sh: please review <VirusChecked>

[Lars Sonchocky-Helldorf]

Hi everybody,

looking forward the GNUstep article in the german C't magazine and the 
echo it might have (lot's of newbees showing interest in GNUstep 
hopefully) I decided to sit down and write (or better: compile) a 
standalone script which checks your system for all the stuff required by 
GNUstep.

But as a matter of fact building GNUstep is not easy for a novice. If you 
for instance miss some important libs you'll not note this until actually 
building GNUstep, what could require you to start over several times - 
very anoying and daunting.
A configure like script that just nothing configures but just checks for 
the required libraries and tools and reports that in a easy understandable 
way to the user (maybe with a hint where to get them) would ease the build 
process very much.

I called this script preflight.sh

Now after some work is done I want to present it to you for review. This 
is an initial version of preflight.sh which still might contain some bugs 
(I hope on you here since I don't own every machine that script is 
targeted for.) and I think still a lot of overhead (code that can be 
removed).

What have I done?
I mainly put together tests that seemed relevant to me from various 
configure scripts (make, base, gui, xgps, xdps). Since I am not that 
experienced I might have some irrelevant tests in it while other important 
test might be missing. Here I need someone who points me to the right 
direction. (I could need a list where the various requirements are pointed 
out togehter with their relevance (e.g. required (GNUstep won't run 
without), recommended (GNUstep runs much better with this), optional (Not 
necessary but good to have))

Don't be afraid of the script. It doesn't write anything to your hard 
disk.

Thanks for your help (or should I say co-work?), Lars
