[Scons-users] --dry-run can still remove files - is this a bug?

[Bill Deegan]

Chris,

So you're not really using it as a variant dir I believe.
The intent with a variant dir is that SCons would control what is in it.
If your earlier computation deposits the file into '.', does that work?
Is the earlier computation done in SCons? or some external tool?
