+>>> Wesnoth User made content Eclipse Plugin <<<
+
+During Google Summer of Code 2010, Timotei Dolean (timotei) has developed the Wesnoth UMC Plugin.
+
+The plugin is in something like a WML IDE. Basically it offers you some features that greatly help anybody who makes User made Content in WML.
+- It has wizards for new campaign, scenario, faction, era and every other wml tag you can think of. You just complete the needed values and it generates the wml (with nice indentation).
+- It has frontends for launching wmltools( like wmllint, wmlscope, wmlindent on files/directories), the wesnoth game, map editor.
+- It has a specialized WML editor, that has syntax highlighting, tag folding and outline, autocompletion, macro "explorer" and so on.
+- It has a 'upload addon' feature that uploads the specified project to the addons server.
+
+For details and information on how to install it go to: http://eclipse.wesnoth.org
