# Description: check linkage of installed keg
# Usage:
# brew linkage <formulae>
#
# Only works on installed formulae. An error is raised if it is run on uninstalled
# formulae.
#
# Options:
# --test - testing version: only display broken libs; exit non-zero if any
# breakage was found.
# --reverse - For each dylib the keg references, print the dylib followed by the
# binaries which link to it.
