[Scons-dev] Support for Tools via a pip package / python module in sys path

[Bill Deegan]

Wouldn't this work and not require any changes?
Or if it doesn't already work, wouldn't that be easier syntax? no
additional arguments, if it's got a '.' in it then you know it's part of a
package?

toollist = ['scons_toollib_example.TestBuilder1']
env = Environment(ENV = os.environ, tools = toollist)
env.TestBuilder1('testdest1.txt', 'testsrc1.txt')

How would you handle overloaded tool names in a module?
For example
scons_toollib_example has a gcc tool?
