[SEAPY] ?: Way to use help to create a list-valued variable...

[David Goldsmith]

...containing, as strings, all installed modules?  (I tried simply x =
help('modules') and it didn't crash, but when it got done, print x just
printed None.) If not, is there a way to do it more "elegant" than
returning a directory listing of site-packages and then filtering that for
just the .py files?  Thanks!
