# checkver [-q] [installedlibdir [library name]]
#
# This script must be run from a directory in which
# a shlib_version file resides.
#
# If no arguments are passed the name of the current directory
# is assumed to be the name of the library. The directory
# "/usr/lib" will be searched for problematic libraries.
#
# A list of directories of installed libraries may be specified.
# This will replace the default of "/usr/lib" and search there
# instead.
#
# An explicit library name may be passed. If present, checkver
# will use this name when searching the installed libraries.
#
# This script produces no output if all library version are not
# large than the source version. If an installed library with a
# version greater than the source is found, checkver prints a
# header and a list of the names of the offending installed libraries.
#
# The header may be supressed by passing "-q" as the first argument.
