[Scons-users] "Targetless" Builder ? Or a target that is not accessible via normal command line / file system.

[Gary Oberbrunner]

Hi Mark; the simplest thing is probably to have the builder also write a
local file ("$TARGET.built" or something).  SCons really needs a file to
use as the target, to tell whether it's up-to-date or not, as well as to
use as a dependency for further builders.
