NAME
       make-first-existing-target - runs make on one of several targets

SYNOPSIS
       make-first-existing-target [-c cmd] target1 [target2 ...] -- [make-options]

DESCRIPTION
       The design of make(1) causes difficulty when you know that a Makefile probably has one of several standardized target
       names, and want build machinery to run exactly one of them, propagating any errors. make(1) will exit 2 if a target
       does not exist, but an existing target may also exit 2 due to some other failure. Makefiles cannot be reliably parsed
       to find targets by anything less Turing-complete than make, and make itself does not provide a way to enumerate the
       targets in a Makefile. It may not even be possible to enumerate the targets in a Makefile without executing part of
       it. (Proof of this is left as an exercise for the reader.)

       This program avoids the problems described above, by attempting to call each specified target in turn, until it
       observes make actually doing something for one of them.

OPTIONS
       -c cmd
	   This can be used to specify the make command to run. Default is "make".

EXIT STATUS
       The exit status is 0 if at least one target existed and was successfully run, and nonzero otherwise.
