Include man pages in the package

[lmoureaux]

Brief summary of issue

gem-plotting-tools has a nice collection of man pages that can be built using make man. However, they are not included in the pip package (didn't check the rpm). I propose to include them.

Types of issue

• Bug report (report an issue with the code)
• Feature request (request for change which adds functionality)

Expected Behavior

• Man pages are installed along with the software
• If needed, the setup script updates the MANPATH

Current Behavior

Man pages are not distributed.

Context (for feature requests)

It's common practice among Linux users to type man command when looking for information about command. We could support this if we installed our man pages.

Agree 100%
If you can focus on setting up the rpm inclusion that would be great.
I don't think it makes sense to add them to a pip package as man pages are system installed, and this will be taken care of by the rpm
For pip packages, we'll rely on the rtd site
