Installwatch is a simple utility which keeps track of which files are
created and modified during the installation of a new program. It's
fast and easy to use. It doesn't require a "pre-install" phase because
it monitors processes while they run. Installwatch works with every
dynamically linked ELF program, by intercepting system calls that
cause file system alterations.
