Remarks
OrionEngine will only install on GNU/Linux platforms at this point. It has been tested on several linux platforms, 32-bit and 64-bit as well. It should work on most *nix'es though, given the correct requirements.
Requirements
Get the source-code
Get the orionengine-common and orionengine-plugins package at
the files section. The next 2 steps should be done with both packages.
Compiling
cd into the orionengine directory, and type './configure' (don't type the quotes). After doing this, type 'make' (again, don't type the qoutes).
Installing
Now, let's install the OrionEngine. To do this you should be root.
Get root access by typing 'su' (yes, you are correct, don't type the qoutes). Make sure to type your root passwd if needed :) . Now simply install it by issueing the command 'make install' (you problably know what not to do by now).
That's it.
