Comment (by strk):

 Regexp for similar thing is really not easy. Rather, can we think of a
 proper
 way to document how to write our SQL in a way to be nice with scripts ?

 Things like: {{{-- Availability / Changed}}} comments, recommendation no
 to
 change signatures, how to deal with upgrades etc..
