[Scons-users] Setting environment variables for scons to use globally on my system

[Björn Pollex]

Benjamin,

you could put the system-specific setup into a global site_init.py.
According to the man-page[1], on Windows, SCons will look in the following
locations by default:

%ALLUSERSPROFILE/Application Data/scons/site_scons
%USERPROFILE%/Local Settings/Application Data/scons/site_scons
%APPDATA%/scons/site_scons
%HOME%/.scons/site_scons
./site_scons

If, in any of these locations, it finds a site_init.py, that will be
executed. Does that help you?

Regards,

    Björn
