To expand on this, if it isn't included in Fedora Core, then shouldn't it be installed in /opt?
It ends up more like:
"If it isn't installed by Fedora's package management system, a package -may- be installed in /opt."
Anything that's using rpm (and registering itself in the system's rpm database) is "OS installed" (installed by the OSs own installation tools).
A third party app with it's own installer might put itself into /opt (all the /opt software I know is complicated third party packages with their own installers).
Packages installed by the local user (usually with ./configure;make;make install) go into /usr/local.
