+	  4.01 Strict and ISO-HTML.
+
+2003-11-24 21:11  ville

+	  twice, some not at all.
+
+2003-11-22 17:40  ville
+
+	* checklink.pl: Check recursion scope also for redirected
+	  documents.

+	* checklink.pl: Make ip_allowed() not choke on URIs that don't
+	  implement host().

+
+2003-09-15 21:31  ville
+
+	* checklink.pl: Unbreak --masquerade, enhance documentation and
+	  error messages.  W3C Bugzilla #340, Debian bug #187791, thanks to
+	  Dan Jacobson and Frederic Schutz for the report.
+
+2003-09-12 20:49  ville
+
+	* checklink.pl: Make the configuration file optional.  Thanks to
+	  Hugo Haas for the heads up.  Also, load Config::General only if
+	  needed.
+
+2003-09-11 13:46  hugo
+
+	* checklink.pl: Fixing the following: [Thu Sep 11 12:44:53 2003]
+	  checklink.pl: Argument "help" isn't numeric in exit at
+	  /home/hugo/bin/checklink.pl line 410.
+
+2003-07-27 19:19  ville
+
+	* checklink.pl: Don't conditionalize the Term::ReadKey requirement,
+	  but defer its loading until actually needed.	system('stty')
+	  doesn't work under -T without laundering $ENV{PATH}, and I don't
+	  feel like going there :P
+
+	  Also, don't load CGI and CGI::Carp in command line mode; defer by
+	  using require() instead of use().
+
+2003-07-27 18:38  ville
+
+	* checklink.pl: Implement option to disallow checking non-public IP
+	  addresses; disallow by default in CGI mode and allow in command
+	  line mode.
+
+	  New requirement: Net::IP.
+
+2003-07-26 22:20  ville
+
+	* checklink.pl: Use Text::Wrap for beautifying command line output,
+	  some other output tweaks.
+
+2003-07-26 22:16  ville
+
+	* checklink.pl: Fix redirect loop detection, and add a descriptive
+	  error message.
+
+	  Previously, only loops like L1 -> L2 -> L3 -> L1 were detected;
+	  ones like L1 -> L2 -> L3 -> L2 resulted in infinite recursion.
+
+	  Fixes <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=188372>,
+	  thanks to Dan Jacobson and Frederic Schutz for reporting this.
+
+2003-07-26 18:48  ville

+	  Frederic's request :)
+
+2003-07-23 23:08  ville
+
+	* checklink.pl: Include POD documentation, courtesy of Frederic
+	  Schutz.
+
+2003-06-16 00:41  ville

+	  make passive mode the default (#226).
+
+2003-06-15 17:56  ville
+
+	* checklink.pl: Trust and launder the NNTPSERVER and NEWSHOST
+	  environment variables in order to support news: URIs without
+	  explicit hostnames under -T.
+
+2003-06-15 17:42  ville
+
+	* checklink.pl: Call get_timestamp always without arguments.
+
+2003-06-02 20:27  ville
+
+	* checklink.pl: -? == --help, be a bit more verbose with the usage
+	  of --location and --recursive (Debian bug report #189642).
+
+2003-05-24 23:32  link
+
+	* checklink.pl: Merging from validator-0_6_0-branch, at tag
+	  validator-0_6_2-beta1, to HEAD.

+	  line options	 (#203, Debian bug #187792).  - Allow bundling of
+	  command line options.  - Bump 2002->2003 in copyright.
+
+2003-02-05 23:47  ville
+
+	* checklink.pl: Skip 'base' tags with empty hrefs (#138).  Put HTML
+	  validity a bit more prominently into beginning of results page.
+
+2003-02-02 21:03  ville
+
+	* checklink.pl: - Implemented external configuration file stuff
+	  (#127).    We now require Config::General >= 2.06.  - Fixed basic
+	  authentication (#122).  If the trusted domain is not specificed,
+	  we only send the authentication to the same host which requested
+	  it.	 Also added a notice about this to the error page/command
+	  line message if    no suitable authentication info was given.  -
+	  Changed text/javascript to application/x-javascript, thanks to
+	  Nicolas Roeser for the report.    (see
+	  <http://lists.w3.org/Archives/Public/www-validator/2003Jan/0158.html>)
+	  - Fixed missing results from the summary when a file:// URI was
+	  present   (also reduces number of error log warnings emitted).  -

+	  cleanups.

+
+	* checklink.pl: - Fix multiple brainos in cookie code.
+
+2002-12-08 16:47  ville
+
+	* checklink.pl: - Rewrote recursion scope checking, was failing
+	  with URIs with no slash after   the hostname; eg.
+	  <http://validator.w3.org> caused checklink to wander to   other
+	  sites (#115).  - Report CVS revision as version number.
+
+2002-12-07 21:55  ville
+
+	* checklink.pl: - Send Accept: application/xhtml+xml, text/html,
+	  */*;q=0.5 (#112) - Sanitize Accept-Language headers; either send
+	  the ones from a browser or *.    In command line mode, really
+	  default to * and send the ones given with    the command line
+	  option. (#110)  - Add messages for codes 303 (#111), 307 and 406
+	  (#55).  - Add "for" attribute for all <label>'s and the
+	  corresponding id's so that   MSIE users can enjoy clicking the
+	  labels.  - Some internal cleanup.
+
+2002-11-23 23:37  ville
+
+	* checklink.pl: - Options can be saved in a cookie (#56).  - Added
+	  a JavaScript check against submitting empty URIs.  - Style
+	  tweaks, ala Validator.  - Point to new docs location (relative).
+
+2002-11-23 17:06  ville
+
+	* checklink.pl: - Tweak "form page" layout.  - Don't say "Valid
+	  anchors!" if no anchors found.  - Fix HTML output from command
+	  line.

+2002-11-22 01:27  ville
+
+	* checklink.pl: Output and style nits.
+
+2002-10-27 15:04  ville
+
+	* checklink.pl: Removed the debug logic and reworked the guess
+	  whether the script is being run as a CGI or from the command
+	  line; the problems this caused outweigh its usefulness [1].  Oh,
+	  and this fixes #26.
+
+	  [1] <http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13914>
+
+2002-10-27 14:08  ville
+
+	* checklink.pl: Unbreak the source download link (introduced in my
+	  previous commit).  Found by checking the output of checklink with
+	  itself.  Yay :)
+
+2002-10-27 12:55  ville
+
+	* checklink.pl: - Load Getopt::Long only in command line mode.	-
+	  Tighter lexical scoping for variables.  - Output version/revision
+	  number consistently everywhere.
+
+2002-10-27 01:43  ville
+
+	* checklink.pl: Use keep-alive if the installed LWP is >= 5.6.
+
+2002-10-27 00:49  ville
+
+	* checklink.pl: - Made W3C::UserAgent more OO avoiding use of
+	  W3C::CheckLink's lexicals.  - Tuned HTTP header sending to make
+	  mod_perl 1.99_05 happy.  - Some style tweaks; reorganized
+	  use()'s, added missing ones.
+
+2002-10-26 22:19  ville
+
+	* checklink.pl: Swap $REVISION and $VERSION in order to be more
+	  consistent with Perl stuff in general, make sure that we have at
+	  least two digits in the version number.
+
+2002-10-26 22:04  ville
+
+	* checklink.pl: Whitespace only (reindentation).
+
+2002-10-26 21:29  ville
+
+	* checklink.pl: Portability update, now actually works on Win2K.
+
+	  Term::ReadKey is now used for reading the password from the
+	  command line if it is available, falling back to stty if it
+	  isn't.
+
+2002-10-23 23:31  ville
+
+	* checklink.pl: Fix all function prototypes, and remove them from
+	  methods.

+
+	* checklink.pl: Got rid of $_contact_address Changed the mailto:
+	  URIs and instructions to include 'checklink' in the subject when
+	  sending a mail to www-validator
+
+2001-03-27 01:46  hugo
+
+	* checklink.pl: Made the "Summary only" function do the same as
+	  John <rowe@excc.ex.ac.uk>'s quiet function from:
+	  http://lists.w3.org/Archives/Public/www-validator/2001JanMar/0261.html
+	  This is a tiny change.
+
+2001-03-27 01:33  hugo
+
+	* checklink.pl: Added a --depth option based on the patch provided
+	  by John <rowe@excc.ex.ac.uk>:
+	  http://lists.w3.org/Archives/Public/www-validator/2001JanMar/0261.html
+
+	  Had to tweak it to make the combination of -r and -D work.
+
+2001-03-27 00:39  hugo
+
+	* checklink.pl: Maybe the base element problem is going to go away
+	  completely now.  I have added a change by John
+	  <rowe@excc.ex.ac.uk> which basically does not trust
+	  HTTP::Response's base function, and it seems to be the way to go.
+
+2001-01-22 18:00  hugo
+
+	* checklink.pl: Fixed typo
+
+2001-01-22 17:58  hugo

+	* checklink.pl: Made it clearer that www-validator is a mailing
+	  list to avoid confusion
+
+2001-01-22 17:49  hugo
+
+	* checklink.pl: Now suggests to send bug reports and comments to
+	  www-validator@w3.org Stopped suggesting people to send me email
+	  when the max number of documents   checked is reached in
+	  recursive mode.
+
+2001-01-19 15:59  hugo
+
+	* checklink.pl: Changed the text before the input box too
+
+2001-01-19 15:52  hugo
+
+	* checklink.pl: Changed title to "W3C Link Checker" only for the
+	  form instead of "W3C® Link Checker: Revision: 2.68 (c) 1999-2001
+	  W3C" which was too verbose
+
+2001-01-18 23:58  hugo
+
+	* checklink.pl: Committing changes that I made a long time ago...
+
+	  - Added 410 HTTP error code in the list of errors.  - Simplified
+	  a few regular expressions (got rid of some /'s).  - Added support
+	  for //... URI's.  - Commented a bit more the code because I was
+	  getting lost.  - Simplified already_processed().  - Added a
+	  --hide-same-realm option: hide 401's that are in the same
+	  realm as the document checked.  - Added a --masquerade option to
+	  check documents on the local system	  as if they were on the
+	  Web (based on a patch by David Carlisle     <davidc@nag.co.uk>).
+	  Example:     checklink -q -b --masquerade
+	  /afs/w3.org/pub/WWW/Math/Group/draft/cr/
+	  http://www.w3.org/TR/2000/CR-MathML2-20001113/ appendixe.html -
+	  500 errors are now split in two cases: DNS problems (LWP reports
+	     that as a 500...) and real internal server errors.  - Fixed a
+	  footer problem in the online problem.  - Fixed a duplicate id
+	  problem in the error code references.
+
+2000-09-25 20:38  hugo
+
+	* checklink.pl: Undid change done in 2.62 about base tag handling.
+	  I'm not really sure why I did this change in the first place, I
+	  might have to fix a bug later...
+
+2000-08-17 18:10  hugo
+
+	* checklink.pl: Replaced require by use and specified that
+	  HTML::Parser version 3 at least is required.
+
+2000-08-15 21:03  hugo
+
+	* checklink.pl: Reverting line list code because it needs tweaking

+	  wrong and was causing a loop in recursive mode)
+
+2000-08-03 21:38  hugo
+
+	* checklink.pl: Discovered the existence of
+	  HTTP::Headers::authorization_basic
+
+2000-07-17 17:26  hugo
+
+	* checklink.pl: Fixed typo
+
+2000-07-14 00:18  hugo
+
+	* checklink.pl: Added links to the documentation
+
+2000-07-13 19:10  hugo
+
+	* checklink.pl: Added a test in the case when the encoding would be

+	  recursive version.  Made things simpler in check_uri().
+
+2000-05-09 22:44  hugo
+
+	* checklink.pl: Next time, I'll think twice before committing: -
+	  Removed superfluous test - Using the same strategy for text
+	  version
+
+2000-05-09 22:36  hugo
+
+	* checklink.pl: Report fragments as really broken is the HTTP end
+	  code is 200
+
+2000-05-07 18:16  hugo
+
+	* checklink.pl: Removed unnecessary test. Added a header for the
+	  link results.

+	  Added a heading for anchors report.
+
+2000-05-05 01:29  hugo
+
+	* checklink.pl: Now uses the version 3 of the API of HTML::Parser.
+	  Got rid of the chunk stuff, since the new parser doesn't care
+	  about the   size of the data parsed (good).  Added attributes
+	  checked. Still not perfect, but better.  Fixed a display bug in
+	  the text version.  Now parses <?xml:stylesheet ...?>. I'm not
+	  happy about the way it's done   though.
+
+2000-05-04 23:28  hugo
+
+	* checklink.pl: Changed language from 'en' to '*'.  Fixed a bug in
+	  the online version when the document cannot be processed.

+	  when an anchor is defined twice on the same line.
+
+2000-04-06 00:28  hugo

+	  a few things.  Changed the email address to report configuration
+	  problems.  Added links to HTML Validator and CSS Validator.

+W3C-LinkChecker
+===============
+
+This distribution contains the W3C Link Checker.
+
+The link checker can be run as a CGI script in a web server as well as
+on the command line.  The CGI version provides a HTML interface as
+seen at <http://validator.w3.org/checklink>.
+
+To install the distribution for command line use:
+
+   perl Makefile.PL
+   make
+   make test
+   make install # as root
+
+To install the CGI version, in addition to the above, copy the
+bin/checklink script into a location in your web server from where
+execution of CGI scripts is allowed, and make sure that the web server
+user has execute permissions to the script.  The CGI directory is
+typically named "cgi-bin" somewhere under your web server root
+directory.
+
+For more information, please consult the POD documentation in the
+checklink.pod file, typically (in the directory where you unpacked the
+source):
+
+  perldoc ./bin/checklink.pod

+=head1 NAME
+
+checklink - check the validity of links in an HTML or XHTML document
+
+=head1 SYNOPSIS
+
+B<checklink>  [ I<options> ] I<URI> ...
+
+=head1 DESCRIPTION
+
+This manual page documents briefly the B<checklink> command.
+
+B<checklink> is a program that reads an HTML or XHTML document,
+extracts a list of anchors and lists and checks that no anchor is
+defined twice and that all the links are dereferenceable, including
+the fragments. It warns about HTTP redirects, including directory
+redirects, and can check recursively a part of a web site.
+
+The program can be used either as a command-line version or as a CGI script.
+
+=head1 OPTIONS
+
+This program follow the usual GNU command line syntax, with long options
+starting with two dashes (`-'). A summary of options is included below.
+
+=over 5
+
+=item B<-?, --help>
+
+Show summary of options.
+
+=item B<-V, --version>
+
+Output version information.
+
+=item B<-s, --summary>
+
+Result summary only.
+
+=item B<-b, --broken>
+
+Show only the broken links, not the redirects.
+
+=item B<-e, --directory>
+
+Hide directory redirects - e.g. L<http://www.w3.org/TR> ->
+L<http://www.w3.org/TR/>.
+
+=item B<-r, --recursive>
+
+Check the documents linked from the first one.
+
+=item B<-D, --depth n>
+
+Check the documents linked from the first one to depth n
+(implies --recursive).
+
+=item B<-l, --location uri>
+
+Scope of the documents checked in recursive mode. By default, for
+L<http://www.w3.org/TR/html4/Overview.html> for example, it would be
+L<http://www.w3.org/TR/html4/>.
+
+=item B<-n, --noacclanguage>
+
+Do not send an Accept-Language header.
+
+=item B<-L, --languages>
+
+Languages accepted (default: '*').
+
+=item B<-q, --quiet>
+
+No output if no errors are found.
+
+=item B<-v, --verbose>
+
+Verbose mode.
+
+=item B<-i, --indicator>
+
+Show progress while parsing.
+
+=item B<-u, --user username>
+
+Specify a username for authentication.
+
+=item B<-p, --password password>
+
+Specify a password.
+
+=item B<--hide-same-realm>
+
+Hide 401's that are in the same realm as the document checked.
+
+=item B<-t, --timeout value>
+
+Timeout for the HTTP requests.
+
+=item B<-d, --domain domain>
+
+Regular expression describing the domain to which the authentication
+information will be sent.  The default value can be specified in the
+checklink configuration file.
+
+=item B<--masquerade "local remote">
+
+Masquerade local dir as a remote URI.  For example, the following results in
+/my/local/dir/ being "mapped" to http://some/remote/uri/
+
+  --masquerade "/my/local/dir http://some/remote/uri/"
+
+As of revision 3.6.2.19 of checklink, --masquerade takes a single
+argument consisting of two URIs, separated by whitespace.  One usual way of
+providing a value with embedded whitespace is to enclose it in quotes.
+
+=item B<-y, --proxy proxy>
+
+Specify an HTTP proxy server.
+
+=item B<-h, --html>
+
+HTML output.
+
+=back
+
+=head1 FILES
+
+=over 5
+
+=item F</etc/w3c/checklink.conf>
+
+The main configuration file.  You can use the L<W3C_CHECKLINK_CFG> environment
+variable to override the default location.
+
+C<Trusted> specifies a regular expression for
+matching trusted domains (ie. domains where HTTP basic authentication, if
+any, will be sent).  For example, the following configures only the w3.org
+domain as trusted:
+
+    Trusted = \.w3\.org$
+
+C<Allow_Private_IPs> is a boolean flag indicating whether checking links
+on non-public IP addresses is allowed.  The default is true in command line
+mode and false when run as a CGI script.  For example, to disallow checking
+non-public IP addresses, regardless of the mode, use:
+
+   Allow_Private_IPs = 0
+
+=back
+
+=head1 ENVIRONMENT
+
+checklink uses the libwww-perl library which has a number of environment
+variables affecting its behaviour.  See L</"SEE ALSO"> for some
+pointers.
+
+=over 5
+
+=item B<W3C_CHECKLINK_CFG>
+
+If set, overrides the path to the configuration file.
