2001-11-03  Hans de Graaff  <hans@degraaff.org>

	message.
	(handle_url): Use status_line instead of code and message for
	HTTP::Response object.

2001-10-25  Hans de Graaff  <hans@degraaff.org>

	* checkbot.pl (init_globals): Initialize last checkpoint time with

	these pages as early as possible.

2001-07-01  Hans de Graaff  <hans@degraaff.org>

	* checkbot.pl (get_server_type): Take into account that we might
	not learn anything about the server

2001-05-06  Hans de Graaff  <hans@degraaff.org>

	that moving to using GET requests only will be easier later.

2001-04-30  Hans de Graaff  <hans@degraaff.org>

	* checkbot.pl (send_mail): Really fix printing of starting URLs in
	email. All URLs are now printed in the subject and body of the

	where printf on a pipe is not implemented.

	important bugfix when dealing with relative redirects.

2001-01-01  Hans de Graaff  <hans@degraaff.org>

	* checkbot.pl (init_globals): If no --match is given, construct

	URLs Checkbot will find and check.

2000-12-24  Petter Reinholdtsen <pere@hungry.com>

	* checkbot.pl (handle_url): Deal with redirect responses without
	Location header.

2000-11-18  Roman Maeder  <maeder@mathconsult.ch>

	* checkbot.pl (handle_url): Remove check which would not check
	files named the same as the main report file. If you don't want
	Checkbot to check its intermediate pages, use the --exclude
	option.

	* checkbot.pl (handle_url): Ask server for file type when
	requesting http:// URLs to be on the safe side, as using
	guess_media_type() is not always correct.

2000-10-28  Nick Hibma  <n_hibma@qubesoft.com>

	* checkbot.pl (check_external): Only print when --verbose is true.
	(printServerProblems): Fix proper printing of <hr>.

	* checkbot.pl (create_page): Add --style option which allows a
	link to a CSS file to be included in each Checkbot page.

2000-08-20  Nick Hibma  <n_hibma@qubesoft.com>

	* checkbot.pl (check_external): Some servers don't set the Server:
	header. Check to see if the server field is set in a response to
	avoid warnings.

	* checkbot.pl (add_checked): Add --enable-virtual option to use
	hostname instead of IP address to distinguish servers. This allows
	checking of multiple virtual servers.

	* checkbot.pl (check_point): Oops, checking would occur every minute

	* checkbot.pl: Switched from short options to long options.
	I was already running out of meaningful options, so before adding
	additional stuff I wanted to move to Long options first. You
	should be able to abbreviate most options to the previous values. 
	Notable exception is -m, which has become --match.

Wed Sep 25 10:58:06 1996  Hans de Graaff  <J.J.deGraaff@twi.tudelft.nl>

	The new LinkExtractor is nice, but I shouldn't treat its output as

	Need further logic to parse gopher returned menu for bad file or
	directory.

	* checkbot: Made a good start with POD documentation inside the
	checkbot file. Try 'perldoc checkbot'.

	* TODO: Added number of suggestions by Luuk de Boer.

	* checkbot (send_mail): Include summary of links checked in message.

Fri Aug  2 13:01:02 1996  Hans de Graaff  <J.J.deGraaff@twi.tudelft.nl>

	* checkbot: 
	Added check for correct LWP version. We now need 5.01, due to bugs
	in the handling of the BASE attribute in previous versions.

Sat Jul 27 21:13:26 1996  Hans de Graaff  <Hans.deGraaff@twi72.twi.tudelft.nl>

	* checkbot:

	Optimized some static regular expressions.

	again.

	Martin Cleaver.

Mon May 27 09:21:30 1996  Hans de Graaff  <Hans.deGraaff@twi72.twi.tudelft.nl>

	* checkbot: oops, small error in regexp caused script to append a
	slash to almost all start-url's. Fixed.
	
	* checkbot (handle_doc): External links without full URL's were
	not always handled properly.

Sun May 26 10:04:39 1996  Hans de Graaff  <Hans.deGraaff@twi72.twi.tudelft.nl>

	* checkbot: If the starting URL doesn't end in a slash, and
	doesn't have an extension, assume we need to add a slash.

	* index.html: Add version number to web page, and make sure it gets
	updated automatically.

Wed May 22 09:58:36 1996  Hans de Graaff  <J.J.deGraaff@twi.tudelft.nl>

        server)

Fri Mar 15 11:06:13 1996  Hans de Graaff  <J.J.deGraaff@twi.tudelft.nl>

	Added 'require 5.002' (because libwww-perl5b8 requires it).

	can be seen as a first step towards fixing the huge
	memory-consumption.

Tue Feb 27 09:57:57 1996  Hans de Graaff  <J.J.deGraaff@twi.tudelft.nl>

	* checkbot:
	Fixed bug which occured when -x option was not present.

	Major rewrite of most of the internal routines. The routines are
	much more structured now, and broken up into smaller routines.

Fri Aug 25 11:23:36 1995  Hans de Graaff  <graaff@is.twi.tudelft.nl>

	* Made a start with the perl5 version of checkbot. The modules in
	perl5 (e.g. LWP) look very promising, and should make checkbot
	quite a bit better.
