For what it is worth, I do this:

foreach d (resample)
	/usr/bin/etags -a -o funsTAGS --regex=@updateTAGSregexp $d/funs/*.q $d/funs/*.qpp
end


where updateTAGSregexp is this file:


/This is a file of regular expressions to be used by updateTAGS/
/First normal names, no subscripting or assignment form/
/Use grouping to get just the name/
/"*\([.A-Za-z][.A-Za-z0-9]*\)"*[ \t]*\(<-\|_\)/\1/
/Now the subscripting versions, must be quoted/
/"[[]+\(<-\)*[.][.A-Za-z][.A-Za-z0-9]*"/
