INSTALLATION USING .TAR.GZ

This is the only install method that allows installation by non-root users.  It is also appropriate for Linux distributions that don't support .deb or .rpm packages.  This method requires manual installation of dependencies, so if your distribution supports .deb or .rpm, you should use those packages instead of .tar.gz.

If you run the .tar.gz installer as root, Beyond Compare is installed system wide.  If you run the .tar.gz installer as a normal user, it is installed in the current user's home directory.
