Stallion is a Python Package Manager interface created to provide an "easy-to-use" visual interface for Python newcomers. Today we have many nice distribution utilities like pip, distribute, etc, but we don't have a nice visual approach with these same goals.

What's new in release v0.2

Bug fixes
Lot's of bugs were fixed:
Global checking feature
Many people asked for a global version updates checking, now you have this feature under the menu "PyPI Repository". This option is going to check updates for all your packages. A new icon will appear on the sidebar packages menu warning in case of a new available update.
Classifiers refactoring
The classifiers of the package are now visually different.

Reporting bug

Open an issue in Github with the traceback. To get the traceback, you'll have to run Stallion in debugging mode:

$ python -m stallion.main -drvi
