# 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.
