     41 # This script must be run from a directory in which
     42 # a shlib_version file resides.
     43 #
     44 # If no arguments are passed the name of the current directory
     45 # is assumed to be the name of the library.  The directory
     46 # "/usr/lib" will be searched for problematic libraries.
     47 #
     48 # A list of directories of installed libraries may be specified.
     49 # This will replace the default of "/usr/lib" and search there
     50 # instead.
     51 #
     52 # An explicit library name may be passed.  If present, checkver
     53 # will use this name when searching the installed libraries.
     54 #
     55 # This script produces no output if all library version are not 
     56 # large than the source version.  If an installed library with a
     57 # version greater than the source is found, checkver prints a
     58 # header and a list of the names of the offending installed libraries.
