5/22/03 - lengthen intf_type, encaps_type and ipx_encaps_type fields
	of intf record and place length checks/truncation in readcfg.pl
	for description and intf_type fields - postgres aborts if
	data exceeds field size.
5/6/03 - change to defaults/rc.wandoc - DBD::Mysql no longer
	accepts IP addresses for db_hostname
5/5/03 - handle IOS bug which places double quotes around hostname
	in config, (but not hostname acquired via SNMP).  Also add
	code in case they add same bug with single quotes.
4/15/03 - loosened up pattern matches in readcfgs.pl to handle
	trailing whitespace, which IOS can sometimes add - thanks to
	Graeme Danielson for the bug report.
2/27/03 - wd1.027 - Larry Hotz reported bug in runwandoc.sh when
	running under Solaris.  Bourne shell does not interpret '!'
	operator internally, needs 'test'.
5/30/02 - wd1.027 - Ulf Heiman reported bug & fix to cleancfgs.pl,
	was leaving off newline when snmp community string was default.
4/17/02 - wd1.027 - Found that version 10.0 config files start with
	a '####' which trips the switch detection in readcfg.pl, fixed.

2/13/02 - wd1.026 - Fix to gendns.pl to handle vlan interfaces (patch
	and bug report from Mike Fisher) and default to 'unk' for unknown
	interface types.  Also, corrected bad logic for acquiring domain name
	in gendns.pl (thanks to Ruediger Biernat for bug report).  Improved
	error checking in cleancfg.pl & runwandoc.sh.  Fix to neighbors.pl
	(11/21/01) to prevent IP secondaries on same net from generating
	dupe entries.  Fix to syslog.pl so that occasional inclusions of
	messages in the wrong net do not occur.  Changes to db schema,
	readcfg.pl, cook.pl and wd1lib.pm in order to handle named ip
	access-lists (thanks to Richard Kesiar for the bug report).
	Fix to readcfg.pl to correct filtering of configs which contain
	"set" commands and better banner handling (thanks to Joe Kazlauskas
	for the bug report).

6/14/01 - wd1.025 - Fix for MSDOS <CR><LF> line separators in config files.
	Fix for perl5/5.6 compatibility (no sprintf("%b") in perl5).  Fix
	for leading zeros in syslog date comparison (another error in 24-hr
	report).  Other syslog fixes (how to handle interface messages for
	virtual interfaces and bad function call) and rtrerr.pl (undefined
	snmp acl) fixes from Mike Fisher.  Minor documentation changes.
	Minor improvements to Install.sh.

5/31/01 - wd1.024 - Simplified 24-hour syslog logic, added more syslog
	parameter tests to wdtest.pl, improved cfg_dir filter in readcfg.pl
	(Mike Fisher's suggestion).  Genrc.pl now checks for pre-existing
	rc.wandoc and offers to exit.

5/31/01 - wd1.023 - Bug fixes for syslog.pl - handled multiple syslog
	message files wrong and couldn't figure out 24-hour report during
	first 9 days of the month.  Minor changes to docs and "explains".

5/30/01 - wd1.021 - Fixes to genrc.pl: mkdir() (2 args are better
	than 1), glob & regexp parms were written to rc.wandoc without
	quotes, link() but no unlink() when storing old rc.wandoc.  Fixes
	to test operator in runwandoc.sh (Solaris compat) and mkdir()
	args in wd1lib.pm.  Thanks to Mike Fisher for the bug report.
