This is a utility for creating deb and rpm packages, signing them

It has two over-arching responsiblities:

1. Create deb and yum repositories from .deb and .rpm files.
|
|
This is also responsible for signing the packages and generally preparing

them to be in an uploadable state.

2. Upload these packages to a storage in a format that apt and yum expect.
