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