title: Python how to share package between multiple projects
body: <p>I have a package that contains protocols for specific hardware from multiple vendors. This is basically a collection of multiple different protocols that have similar interface. It is ported to python by me. But now I have two projects that handle communication with this equipment using different transport protocols one is over TCP another is over RS-485/232. How to share the package with protocols between this two projects so that I don't need to copy it after I add new functionality support or bug fixes.</p>
