For naming, I must confess I find it a bit strange that while all other
constraint types use ordinary English names ("order", "location",
"colocation"), this one uses a rather strange looking abbreviation.
However, I'll also concede that the only alternative that currently
comes to my mind would be to rename the constraint type to "ticket", but
that obviously creates ambiguity between ticket the constraint and
ticket the thing that booth manages, so it would probably be worse.
Perhaps others have a better idea.

About the documentation, I generally find it very useful; I only have
one addition for a suggestion: it's not immediately clear from the
existing docs that multiple resources can depend on the same ticket. It
does mention resource sets (which, still, could use an additional
sentence à la "thus, multiple resources can depend on the same ticket"
as a courtesy to the novice reader), but it doesn't say whether it's OK
to have multiple constraints referring to the same ticket.

If I can spare the time some time in the next few weeks I might also
prepare a "die, passive voice, die" patch for that documentation page,
but that's just a pet peeve of mine. :)

Cheers,
Florian
