Problem

PyCharm and IntelliJ IDEA use the .idea directory to keep project information. While the two seem to be able to read each other's files, they (currently) don't understand the other's settings.

Solution

The work-around (till they learn to play better with each other) is to keep their .idea folders separate, while sharing a common project source tree. Instructions follow below.
