I switched from NAnt to using Python to write build automation scripts.  I am curious if whether any build frameworks worth using that are similar to Make, Ant, and NAnt, but, instead, are Python-based.  For example, Ruby has Rake.  What about Python?
My Rapid Throughts:
SCons is quite mature and oriented also to other languages (es C++)
Waf is very simlar to ant/maven, so you will prefer it if you are used to ant/maven
Paver is very pythonic oriented, and seems a good option if you do not know how to start.
Are there any good build frameworks written in Python?
