Comment (by rhaas):

 When you say "tells Cactus that thorn is ready" do you mean "cactus
 thornlib or make.checked target depends on this so that thornlib or
 make.checked is updated triggering dependent thorns to rebuild
 themselves"?

 For 'available' it says "is created and/or updated whenever detection is
 run and something was detected." does that mean "available" is not touched
 if detection is run and nothing was detected (this would seem to be in
 direct contradiction of "tells the make system whether build.sh needs to
 run, i.e., whether after detection a build is necessary. ")? Which script
 creates/touches 'available'? Only detect.sh or sometimes also build.sh?
