+h2.  Why Plugins for Mongrel?
+
+If you've ever used other systems that have plugins you'll find there are
+several painful parts to writing your own plugin:
+
+* You don't have their developer tools so it takes forever to get started.
+* You don't know how to structure the project or even where to start.
+* Once you get it built you have to figure out how to register and install it.
+* When you want to update it you have to somehow get the update out to users.
+* You have to manage dependencies between your plugin and other plugins.
+* Including and using your own resources (images, html files, etc.) or config files
+  is really painful.  Not sure why this is but it's really annoying.
+
+Most people solve many of the problems by the "sourdough method".  They
+take a plugin that currently works, copy it, and base their plugin
+on the prototype.  This works great until you want to do something 
+original or until you find out the original author did something wrong.
+
+GemPlugin solves this problem by relying on the regular RubyGems
+package management system to give you:
+
+* A simple way to package, distribute, manage, and update your Mongrel plugins.
+* Dynamic loading based on the gem dependencies and not on specific configurations.
+* Segregated extensions for Mongrel in case you want a different license than LGPL.
+* All the capabilities of RubyGems.  GemPlugin doesn't mess with them at all.
+* A little generator that starts your project off right similar to how Rails generators work.
+* The ability to package resources (images, configs, etc.) with your gem and then load them
+  dynamically no matter where the gem eventually gets installed.
+
+In the end GemPlugins are just RubyGems that get loaded a special way 
+so they are activated right away.  The only extra thing is a bit of
+"magic" that puts plugins into a nice little namespace outside of
+the usual Ruby module and class hierarchy.
+
+The advantage for Mongrel is that people can write their own
+plugins and distribute them easily without anything more complex
+than what all Ruby developers already have:  RubyGems.
+
+h2.  How They Work
+
+Mongrel plugins (a.k.a. GemPlugins) are really very simple.  Basically
+when you use the GemPlugin API you tell it what kind of dependencies
+will trigger a gem to be loaded.  GemPlugin then goes through all of 
+the installed gems and loads any that meet the dependency description.
+Then your plugin just registers itself in the right "plugin category"
+and everything starts working.  The user of your plugin won't have to
+do too much unless you want to give them additional configuration.
+
+The best way to understand this is to actually build a plugin 
+and watch it work.

+h2. Mar-12:   Mongrel 0.3.10 -- Big Release Day
+
+This release is a bigger release than those in the
+past but it was necessary as it touched many little
+parts of the code base and includes a more complete
+GemPlugin functionality.  This release features the 
+following changes:
+
+* GemPlugin now supports including and easily finding resources and config files
+  you package with your gems.
+* GemPlugin loading doesn't use any deprecated RubyGems APIs.
+* GemPlugin comes with a generator called *gpgen* that will make it easy to start off 
+  a plugin project.
+* A complete document on "Writing A Mongrel Plugin":/docs/gem_plugin.html that
+  also explains how they work.
+* The "Mongrel Config Tool":/images/config_tool_snap.png that demonstrates
+  building a useful command for controlling a Mongrel server.
+** It uses a "Camping":http://camping.rubyforge.org/ to present an interface.
+** Demonstrates combining Camping handlers with Mongrel handlers.
+** Shows how to use the new GemPlugin resources API to include ERB templates, images,
+   and CSS stylesheets which are loaded out of the gem (no external install needed).
+* Restructuring of the project source a bit to support testing all the 
+  default plugins and to make building much easier.
+* Properly loads any gems that depend on Rails (including GemPlugins) until the
+  very last minute after Rails is loaded and configured.
+* A slight hack courtesy of Sean Treadway which jacks up the default server
+  listen queue from 5 to 1024.  This should work on all platforms where 
+  available and should improve concurrency for everyone.
+* A more complete and useful Camping postamble that makes it the same size
+  as the WEBrick one.  Also makes sure that Camping handlers and Mongrel
+  handlers can live in peace together.
+
+There's also a bunch of bug fixes:
+
+* Should work well with edge rails now and tries to be very nice.
+* It holds of Rails configuration until the absolute latest time to
+  avoid having the daemonize call from closing log files Rails opens.
+* Tweaks to the API docs in various places and cleaned out dead code.
+* Lots of fixes to the build.  If you get the source and are on Unix
+  you can just do "rake install" to install the whole thing via gems.
+
+This release has been tested on Linux, OSX, and FreeBSD with only
+light testing on Win32.  I'll be making the 0.3.11 release Win32
+specific so that the config tool can be useful for those folks too.
+
+Otherwise this is a large release so please grab it and test like
+mad.
