ppic is python package information collector.
if your environment is such as below. :
$ pip freeze
SQLAlchemy==0.9.7ppic command can collect information that need available updates are existed or not. :
$ ppic sqlalchemy ansible
collection information .. takes at least 0.05 sec
{ 'packages': [ { 'name': 'SQLAlchemy',
'_previous_version': '0.9.7',
'version': '0.9.8',
'last_modified': '2014-10-13T17:16:15'},

'last_modified': '2014-12-04T23:16:25'}],
'update_candidates': ["SQLAlchemy: '0.9.7' -> '0.9.8'"], # update is found.
'new_install_candidates': ["ansible: '' -> '1.8.2'"]} # ansible is not found in your environment--installed option with ppic then collect all information in your in environment. :
$ ppic --installed
collection information .. takes at least 0.00 sec

'version': '0.9.8',

'update_candidates': ["SQLAlchemy: '0.9.7' -> '0.9.8'"], # update is found.
'new_install_candidates': []}--stable-only option with ppic then collecting stable version only(but this is heuristic aproach maybe wrong, maybe)
