46 # -d: Checks the version against the installed libraries.

48 # used as the location of installed libraries.

50 # -s: Checks the version against the sets. If no argument
51 # follows the sets directory defaults to "/usr/src/distrib/sets/lists".
52 # The directory may be specified as either the top of the
53 # source tree or as the lists directory.

55 # -f: Checks the version against the provided list. A filename
56 # must be supplied.

61 # This script produces no output if all library version are not
