Version scripts provides information that can be used by GNU/Linux distribution packaging tools. For example, Debian has a tool dpkg-shlibdeps that can determine the minimal required version of each dependency (by looking at the symbol list) and stuff the information into the Debian specific packaging files. We can utilize such feasture to reduce the size of shared library as well.
