## Author Notes:
## Use this mod together with the manage bots mod already included with integramod
## Make backups and test this on a test forum if you can. This is not a typical mod.
## This version is not like all the other mod rewrite and search engine optimization mods
## out there. It will make your urls into keyword phrases. to do this it rewrites the url
## to look like the topic or forum title.
## To see this mod in action please goto:
## http://www.webmedic.net/index.php
##
## LICENSE:
## Due to some issues with others taking my work and not offering proper credit
## (in as much as they have removed my credits and added their own) I have added
## a LICENSE.TXT. I have decided to license this under the RPL which states you can not
## remove my credits and if you make any modifications you have to resubmit the modifications
## to me for includion into this toolkit again. You can read the license for yourself for
## further info. It is also an open source license that has been deemed ok by osi.
##
## Along with this I now require a link to use this mod. If you don't want to have the
## linkback I will remove the requirement for a linkback for a small fee. If you are
## interested in removing the link please contact me at bah@webmedic.net
##
## All previous versions are licensed under the rpl from 6/29/2005

## MOD History:
##
##   2005-08-14 - Version 2.3.0
##    - Fixes for header errors and code clean up
##    - Added new characters to make url friendly function
##    - I went up a whole revision number as there were quite a few little bug fixes.
##      I also want to start a new thread for this.
##
##   2005-07-15 - Version 2.2.3
##    - small fix for some header issues.
##
##   2005-07-03 - Version 2.2.2
##    - Dissabled some of the page optimizations to fix issues with some javascripts
##      and css.
##    - Added keyword meta tags to the zip.
##
##   2005-06-29 - Version 2.2.1
##    - Added LICENSE.TXT after finding a few other sites taking credit for this mod.
##     - Added footer text for usage of this mod.
##    - Changed order of the install to help with any errors that may occur durring install.
##    - Fixed a few issues with overly optimizing the pages.
##
##   2005-06-24 - Version 2.2.0
##    - Rewrote some of the code for the smartor album again. This time it is more
##       comprehensive and should fix even unforeseen issues.
##    - Added new features so that when the page is being gziped it also removes
##       Unwanted comments, spaces, tabs, line feeds, and carriage returns. This also
##       makes the page smaller and helps to speed things up.
##
##   TODO: Fix forward and back links as well as links within threads that have multiple pages.
##
##   2005-06-21 - Version 2.1.0
##    - Rewrote a good portion of the smartor album code so that it works better.
##    - Added support for categories hierarchy thanks to 993ti at the
##       www.webmedic.net forums.
##    - Fixed major bug with phpbb were gzip was not working properly at all ever.
##       This mod fixes that issue so that gzip encoding now works properly.
##
##   2005-06-19 - Version 2.0.2
##    - Fixed small issue with " showing up in the url as -quot-
##      This was due to phpbb changing " to &quot; which is correct
##      but still does not look good in a url. So now it is completely removed.
##
##   2005-06-14 - Version 2.0.1
##    - Fixed small issue with url's not being rewritten if the site was using gzip compression.
##    - Fixed some of the string replace entries to not look for more than one space
##    - added < and > to the string replace functions
##
##   2005-06-07 - Version 2.0.0
##    - Added ability to use with pafiledb mod
##    - Added ability to use with kb mod (NOT WORKING YET)
##    - Added ability to use with Smartor album mod
##    - Added German umlauts & special characters (thanks to m³)
##    - Modified the way links are generated somewhat.
##      Hopefully the new method will catch a few things the old one did not.
##
##   2004-11-03 - Version 1.1.0
##    - Added replacements for /, \, and foreign character sets.
##
##   2004-08-22 - Version 1.0.0
##      - Initial public release.
