[Scons-users] Is it possible to use Copy Action Functions outside of SConscript?

I tried both solutions but still no luck. It appears that scons does not
like the Copy inside the Command builder :
env.Command(target = tgtCpp + tgtH + ccpp,
source = idlFile,
action = [Copy(os.path.join(env['LOCALROOT'],
variantDirOutput, idlFile), idlFile),
'idlpp -S -l cpp -d ' + variantDirOutput + '
$SOURCE'])
I am am calling directly
Copy(os.path.join(env['LOCALROOT'], str(env.Dir('.').path), 'MaxSim.idl'),
Glob('*.idl')[0])
scons is OK
