43# This script must be run from a directory in which
44# a shlib_version file resides.
45#
46# One of -d, -s or -f must be specified.
47#
48# all: If library name is not specified it is assumed to
49#	be the name of the current directory.
50#
51# -d: Checks the version against the installed libraries.
52#	If no further arguments are given "/usr/lib" is
53#	used as the location of installed libraries.
54#
55# -s: Checks the version against the sets.  If no argument
56#	follows the sets directory defaults to "/usr/src/distrib/sets/lists".
57#	The directory may be specified as either the top of the
58#	source tree or as the lists directory.
59#
60# -f: Checks the version against the provided list.  A filename
61#	must be supplied.
62#
63# This script produces no output if all library version are not
64# large than the source version.  If an installed library with a
65# version greater than the source is found, checkver prints a
66# header and a list of the names of the offending installed libraries.
67#
68# The header may be supressed by passing "-q" as the first argument.
