[Scons-users] creating custom builder

[Ringo De Smet]

Hello Wiktor,

First of all, I suggest you study some of the contributed custom builders
found on the wiki (source included):
http://scons.org/wiki/CustomBuilders

This should definitely help you further.

You use an emitter for that. Read in the man page under "Builder Objects"
the section about emitter:

Have a look at the AutoConfigBuilder or MakeBuilder in the list of
contributed Custom Builders. These builders accept additional keyword
arguments.

Make an Alias for the list of targets. See Alias() under "Methods and
Functions to do things"

Hope this helps,
