Question about bksys

[Scott Newton]

One of the questions that passed through my mind while I was doing the lua 
module was - What happens in the case where you have two programs, one with 
an optional dependency and one with a required dependency on say lua?

I was thinking that maybe generate(env) should return two parameters, 
found_or_not_found and reason_for_exiting.

Then the SConstruct file could have:

modules : 'a b c'
optional : 'd e f'

That way you could have the same checks independent of whether the module is 
optional or not, with a interface between generate and where it is called 
from either allowing the build to continue or exiting with the given 
reason_for_exiting.

The other advantage of this would be the ability to build up a CPAN type 
collection of scons checks which developers could mix and match. As I see it 
now the developer would have to change the check depending on whether the 
check was optional or required for their program.

Am I missing something or would this be something worthwhile? If it is then 
I'm happy to doing the coding.

Thanks
