the API is important.

Because everything should have a man page

as I figure out how logging/output might look.  A couple of major TODO features
also listed in the file.

this by having a changed=True/False in the JSON for these modules.  Added a note
so folks won't think we can only execute shell :)

constants file so as to not repeat constants between CLI and lib.

adds an option to ask for and store the ssh password from the cli

Don't use a shell and thus avoid a whole class of problems

Use a mktemp'd path for uploading modules

Fall back to standalone simplejson module

CentOS5 has python 2.4 which doesn't have a built-in json
module
