Clear4Amiga or Clear code for Amiga is plugin intended to clear HTML code generated with Joomla!, to strip codes not compatible with HTML 3.2 or HTML 4.0.
Plugin will clear code only for selected Web browsers so data will be altered only for e.g. older or mobile browsers.
In combination with compatible template same site and same articles can be CSS formated for modern browsers and converted to HTML 3 for ancient browsers.

Plugin sould work with Joomla! 2.5.x (1.6, 1.7), up to version 3.x.
This system plugin should be last in the list so it can filter final HTML codes.

Settings have one text field and several radio buttons.



In text field strings, or substrings of HTTP user agents should be written each in own row.
For example

Amiga-AWeb
IBrowse
AmigaVoyager

will filter page only if request is send from selected browser.
