    I think this may need updating? I mgeaand to get it to work but not by following the directions. When following the directions at plugin page I get errors that it can not find career-builder-*-.php files. I had to copy a lot of the files from the plugin folder directly to my template folder in order for it to work. The Accordion JS wouldn't work either, kept saying it was undefined even though my page source showed it was pulling in the JS file from the plugin folder. Adding just a search box using the method mentioned also gave an error msg. I mgeaand to get what I needed out of it but wanted to report my findings because this is a very good plugin!

    0.3 is not IDEA 7 compatible but you just need to copy the following file in the apiComparator plugin folder (by default ${USER_HOME}\.IntelliJIdea70\config\plugins\apiComparator\lib)
    asm-all-2.2.3.jar : found here

    Very nice and useful plugin. It whould be great improvement if compared code may be associated with appropriate sources and navigation to source/view java doc feature was provided.

    Good plugin, but version is not usable on Demetra. This is one of the plugins I still use Irida for.
