#: * `linkage` [`--test`] [`--reverse`] <formula>:
#: Checks the library links of an installed formula.

#: Only works on installed formulae. An error is raised if it is run on
#: uninstalled formulae.
#:
#: If `--test` is passed, only display missing libraries and exit with a
#: non-zero exit code if any missing libraries were found.
#:
#: If `--reverse` is passed, print the dylib followed by the binaries
#: which link to it for each library the keg references.
