I tried aap-latest.zip with python 2.2.2 under cygwin.
I got error:
  > aap -f ftp://ftp.vim.org/pub/vim/runtime/main.aap
  "main.aap" exists, overwrite? (y/n) y
  Aap: Attempting download of  "ftp://ftp.vim.org/pub/vim/runtime/main.aap"
  Aap: Error in recipe: Cannot download 
"ftp://ftp.vim.org/pub/vim/runtime/main.aap" to "main.aap":
[Errno 2] No  such file or directory: '/home/Administrator/.netrc'

I did 'touch ~/.netrc' and aap proceeded without errors. Is it possible
to avoid errors if ~/.netrc is not present ?
