39# checkvers [-q] [systemlibdir [library name]]
40#
41# This is a wrapper script around checkver.  It will find
42# all directories withing the current directory containing
43# a shlib_version file and call checkver for each.
44#
45# As with checkver, a list of directories of installed libraries
46# may be specified.  This will replace the default of "/usr/lib"
47# and search there instead.
48# 
49# A library name may also be specified.  However, this script
50# will not work correctly if it finds shlib_version files
51# corresponding to a different library.
52#
53# This script produces no output if all library version are ok.
54# If the versions aren't ok the header will be displayed once
55# followed by a list of problematic libraries.
