One way would be to use the locals() [1] to get rid of the exec:
if __name__ == '__main__':
print __doc__
print "\nFUNCTIONS:\n"
for x in __all__:
print x
print locals()[x].__doc__
However, if you just want to call help, calling it on '__main__' seems
to work:
if __name__ == '__main__':
help(__name__)
