Make Tracker manual pages readable online
Tracker provides 'man' pages for all our tools. However we can only view this documentation from the commandline, we can't link to it from online documentation. Because of that, some of the info is duplicated in the wiki, and some of the manual pages are out of date.
I propose that we convert the manual page sources into Markdown format, and use Ronn to convert them at compile time. This would effectively convert them into online documentation that could be viewed directly in GitLab.
