  43 # all: If library name is not specified it is assumed to
  44 #       be the name of the current directory.
  45 #
  46 # -d: Checks the version against the installed libraries.
  47 #       If no further arguments are given "/usr/lib" is
  48 #       used as the location of installed libraries.
  49 #
  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.
  54 #
  55 # -f: Checks the version against the provided list.  A filename
  56 #       must be supplied.
  57 #
  58 # -v: Specify the filename of the shlib_version file.  Defaults
  59 #     to "./shlib_version".

  61 # This script produces no output if all library version are not
  62 # large than the source version.  If an installed library with a
  63 # version greater than the source is found, checkver prints a
  64 # header and a list of the names of the offending installed libraries.
