For people who manage their home directories with things like vcsh or
other versioning system, it's good to know where configuration files
live. This CL adds a FILES section to the man page.
In some cases the display names change so the profile matching fails.
This commit introduces the "--match-edid" option, that allows one to
specify that the profiles matching should be done based on display edid.
This is done by updating the profiles after loading, based on current
display name/edid mapping requested using xrandr.
