jEdit plugins can be installed in two ways: as a system plugin or as a user plugin. Below are instructions for installing plugins under UN*X and
                 Win32. If anyone can give me good instructions for any other platforms, email them to me and I'll put them up here as well.

                 Starting with jEdit 2.2, the system and user plugin directories can always be determined from the Activity Log. On startup, jEdit scans the
                 system and user plugin directories for JAR files to load. Before doing so, it prints the line 'Scanning directory: dir-name' in the Activity Log.
                 The first occurence is the system plugin directory, the second occurence is the user plugin directory.

                 [ System Plugins ]

                 UN*X: Extract the plugin in the 'jars' subdirectory of your jEdit source directory and run 'make install'. This will install the new plugin in
                 your $JEDIT_HOME/jars directory.

                 Win32: Extract the plugin into the 'jars' subdirectory of your installation directory (typically 'C:\Program Files\jEdit\'). The plugin will be
                 loaded next time you run jEdit.

                 [ User Plugins ]

                 On all platforms, user plugins should be installed in the '.jedit/jars' subdirectory of your 'user.home' directory. If you don't know what your
                 'user.home' directory is, you can download this mini-app, TestUserHome.class, and run 'java TestUserHome'. it will output something like 'User
                 home: DIRECTORY'. If this is just too complicated, try the platform-specific instructions below. (oh yeah, here's the source)

                 UN*X: Extract the plugin into the '.jedit/jars' subdirectory of your $HOME directory. The plugin will be loaded next time you run jEdit.

                 Win9X: Extract the plugin into the '.jedit/jars' subdirectory of your %JAVA_HOME% directory. The plugin will be loaded next time you run
                 jEdit.

                 WinNT: Extract the plugin into the '.jedit/jars' subdirectory of your user home directory (%WINDIR%\Profiles\USER). The plugin will be
                 loaded next time you run jEdit.
