[Scons-users] Trying to use Execute()

[Tom Tanner (BLOOMBERG/ LONDON)]

Can't you try using env['PSPAWN'] - there's a builder which does that (I forget which though).

Redirect the output to a file, add the file to the list of outputs in the builder's emitter.
Create another builder to process that file.


That's really inconvenient. 
Couldn't we subclass Execute an make it return a stderr or stdout object?
Is there interest in something along this lines?
