Finding the D compiler programatically.

[Nathan Petrelli]

My program needs to call DMD / GDC to compile a generated class. So, how can I find where the user installed it's dmd.exe / gdc on windows and linux?

Right now I'm checking the following paths to see if it exists:

C:\dmd\bin\dmd.exe
C:\Program Files\dmd\bin\dmd.exe
any folder in %PATH%

and similar algorithm for GDC on linux but it doesn't seems like a very good idea to check all those paths.

Is there a better way?

Thanks.
