i have eclipse
Eclipse IDE for Java EE Developers
Eclipse IDE for C/C++ Developers
Eclipse for PHP Developers
Pulsar for Mobile Java Developers
but how can i merge them and have a single interface just by changing perspective rather as if i have installed them from the update site as a plug-in can i just move all the files from each of them and put them in the plugins folder that is found in
a@a $ ~/.eclipse/org .../plugins
