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

[Mark Ribau]

What I'm trying to avoid is copying extra files to the devkit, since this
is a major bottleneck. The devkits only have 100 megabit connections.
 Copying any amount of large data takes forever.  Our builds are typically
10GB or more in total size.  Avoiding copying over files that are already
up to date would be preferred.
