  33 # checkvers [-q] [systemlibdir [library name]]
  34 #
  35 # This is a wrapper script around checkver.  It will find
  36 # all directories withing the current directory containing
  37 # a shlib_version file and call checkver for each.
  38 #
  39 # As with checkver, a list of directories of installed libraries
  40 # may be specified.  This will replace the default of "/usr/lib"
  41 # and search there instead.
  42 #
  43 # A library name may also be specified.  However, this script
  44 # will not work correctly if it finds shlib_version files
  45 # corresponding to a different library.
  46 #
  47 # This script produces no output if all library version are ok.
  48 # If the versions aren't ok the header will be displayed once
  49 # followed by a list of problematic libraries.
  50 #

  52 # checkvers:
  53 #       if "-s", build list, pass with -f to checkver.
  54 #       if "-d", build list, pass with -f to checkver.
  55 #       if "-f", pass with -f to checkver.
