        Err, don't believe all you read.
__> cat notargetfoo.mk 
        @echo nothing to see here
__> cat withfoo.mk 
all: foo
        @echo something to see here
        @echo doing foo

        Of course, this kinda presupposes that ./debian/rules is a
 makefile -- which is what poicy requires it to be. So we can indeed
 detect if a target foo exists -- just that dpkg folks were trying not
 to depend on the rules file actually being a makefile, as opposed to
 something merely having a similar api to a real make file.

The sheep that fly over your head are soon to land.
