[Pydev-code] Questions (Ant, lint, refactoring)

[S. D. R. <s_d...@ho...>]

Hello all.
  I've searched Google a bit to try and understand what Ant, Lint and
Refactoring do.  I'm not a progammer, but I'm having fun hacking together a
Python/wxPython  program or two.  I've recently begun using Eclipse 3.1 &
pydev.

  I don't understand what these do (ant, lint, and refactoring).  I'm hoping
someone can explain their use to me.  What I read on the internet didn't
have any meaning for me.

Thanks!
Dave
