MAME's Linux documentation - aka the MAN files:https://github.com/mamedev/mame/tree/master/docs/man
Could one of our friendly Linux devs or package maintainers please check that the MAN files are still in sync with https://github.com/mamedev/mame/tree/master/docs/source
at some point? And if not, re-sync them?
It doesn't need to be right away, but it would be nice to know if they were in sync. We do have people who tend to look after such things but most of them are Windows users.
