For the impatient: Select Help > Software Updates... in Eclipse, add the update site http://e-p-i-c.sf.net/updates/testing and follow the on-screen instructions.
Before installing EPIC you need Eclipse, Java, and Perl on your system. An optional PadWalker module is needed for debugging. For details read the system requirements section of the FAQ.
The installation and upgrades are best performed using the Eclipse Update Manager. The Update Manager connects to the EPIC update site, downloads the necessary files and stores them in the plugins and features subfolders of your Eclipse home directory. An older version of the update site can also be downloaded from the EPIC project page at SourceForge and stored locally for offline installation.
The following description applies to Eclipse 3.4 and newer. Older versions have a slightly different looking Update Manager dialogs.
After starting Eclipse select Help > Software Updates... from the menu and switch to the Available Software tab. Click the Add Site... button and enter:
Alternatively, if you have downloaded and unpacked the update site manually, click on Local... in the Add Site... dialog and point to the update site folder.
Tick the newly created site and press the Install... button. Follow the instructions of the install wizard. The warning about the installation of an unsigned feature can be ignored. After installation Eclipse has to be restarted.
Now the installation of EPIC should be complete. For further information, read the EPIC User's Guide in Eclipse's online help or download it as a printable PDF file.
Important: Due to a problem in third-party software Windows and ActiveState Perl users may need to apply this workaround to make debugging in EPIC work!
