XiMera is a virtual CDrom software for linux written in C++ and using Qt4. It is more or less a frontend for the mount command. After launching it will stay in system tray for ulterior use.
Currently XiMera supports only ISO images but other image type support is planned. (via cdemu and nrg2iso)
If you want a very quick install just copy paste these lines into your shell (you have to be in the folder containing ximera.pro file:
qmake && make
mkdir ~/bin && cp ximera ~/bin
sudo perl install.pl
