The community version of this product is definately there to tease the user into trying the $300.00 version of the software. The capabilities of the community server are not worth the effort of installation. The cool stuff, like the ability to suck in an existing C or C++ project aren't turned on. <sigh>.
The so-called community edition of this software is actually crippleware. It's only purpose as far as I can see is to try to draw the user into purchase of one of the fully capable versions of the software. Unless you wish to invest in a non-free license, avoid wasting time with this software.
An open, cross-platform journaling program.
A scientific plotting package.
