 ---++ Overview
 
-You can add plugins to extend TWiki functionality, without altering the core code. A plug-in approach lets you:
-
-   * add virtually unlimited features while keeping the main TWiki code compact and efficient;
-   * heavily customize an installation and still do clean updates to new versions of TWiki;
-   * rapidly develop new TWiki functions in Perl using the plugin API.
-
-Everything to do with TWiki plugins - demos, new releases, downloads, development, general discussion - is available at TWiki.org, in the <b> TWiki:Plugins </b> web.
-
-TWiki plugins are developed and contributed by interested members of the community. Plugins are provided on an 'as is' basis; they are not a part of TWiki, but are independently developed and maintained.

-Each TWiki plugin comes with its own documentation: step-by-step installation instructions, a detailed description of any special requirements, version details, and a working example for testing. Many plugins have an install script that automates these steps for you.
+Each Foswiki plugin comes with its own documentation: step-by-step installation instructions, a detailed description of any special requirements, version details, and a working example for testing. Many plugins have an install script that automates these steps for you.
 
 *Special Requirements:* Some plugins need certain Perl modules to be preinstalled on the host system. Plugins may also use other resources, like graphics, other modules, applications, and templates. You should be able to find detailed instructions in the plugin's documentation.
 
-Each plugin has a standard release topic, located in the TWiki:Plugins web at TWiki.org. There's usually a number of other related topics, such as a developers page, and an appraisal page.

 #PreTesting
 ---+++ On-Site Pretesting
 
-The recommended approach to testing new plugins before making them public is to create a second local TWiki installation, and test the plugin there. You can allow selected users access to the test area. Once you are satisfied that it won't compromise your main installation, you can install it there as well.
-
-InstalledPlugins shows which plugins are: 1) installed, 2) loading properly, and 3) what TWiki:Codev.PluginHandlers they invoke. Any failures are shown in the Errors section. The =[[VarFAILEDPLUGINS][%<nop>FAILEDPLUGINS%]]= macro can be used to debug failures. You may also want to check your webserver error log and the various TWiki log files.

 ---+++ Some Notes on Plugin Performance
 
-The performance of the system depends to some extent on the number of plugins installed and on the plugin implementation. Some plugins impose no measurable performance decrease, some do. For example, a Plugin might use many Perl libraries that need to be initialized with each page view (unless you run mod_perl). You can only really tell the performance impact by installing the plugin and by measuring the performance with and without the new plugin. Use the TWiki:Plugins.PluginBenchmarkAddOn, or test manually with the Apache =ab= utility. Example on Unix:%BR% =time wget -qO /dev/null <nop>%SCRIPTURLPATH{"view"}%/%SYSTEMWEB%/AbcPlugin=

 ---+++ Discussions and Feedback on Plugins
 
-Each published plugin has a plugin development topic on TWiki.org. Plugin development topics are named after your plugin and end in =Dev=, such as =MyFirstPluginDev=. The plugin development topic is a great resource to discuss feature enhancements and to get feedback from the TWiki community.

----+++ Maintaining Compatibility with Earlier TWiki Versions
-
-The plugin interface (TWikiFuncDotPm functions and plugin handlers) evolve over time. TWiki introduces new API functions to address the needs of plugin authors. Plugins using unofficial TWiki internal functions may no longer work on a TWiki upgrade.
-
-Organizations typically do not upgrade to the latest TWiki for many months. However, many administrators still would like to install the latest versions of a plugin on their older TWiki installation. This need is fulfilled if plugins are maintained in a compatible manner. 
-
-__%T% Tip:__ Plugins can be written to be compatible with older and newer TWiki releases. This can be done also for plugins using unofficial TWiki internal functions of an earlier release that no longer work on the latest TWiki codebase. 
-Here is an example; the TWiki:Support.PluginsSupplement has more details.

 ---+++ Handling deprecated functions
 
-From time-to-time, the TWiki developers will add new functions to the interface (either to TWikiFuncDotPm, or new handlers). Sometimes these improvements mean that old functions have to be deprecated to keep the code manageable. When this happens, the deprecated functions will be supported in the interface for at least one more TWiki release, and probably longer, though this cannot be guaranteed.
-
-When a plugin defines deprecated handlers, a warning will be shown in the list generated by %<nop>FAILEDPLUGINS%. Admins who see these warnings should check TWiki.org and if necessary, contact the plugin author, for an updated version of the plugin.
-
-Updated plugins may still need to define deprecated handlers for compatibility with old TWiki versions. In this case, the plugin package that defines old handlers can suppress the warnings in %<nop>FAILEDPLUGINS%.
-
-This is done by defining a map from the handler name to the =TWiki::Plugins= version _in which the handler was first deprecated_. For example, if we need to define the =endRenderingHandler= for compatibility with =TWiki::Plugins= versions before 1.1, we would add this to the plugin:
-
-<verbatim>
-package TWiki::Plugins::SinkPlugin;
-use vars qw( %TWikiCompatibility );
-$TWikiCompatibility{endRenderingHandler} = 1.1;
