RANLIB(1)
NAME
ranlib − convert archives to random libraries
USAGE
ranlib archive ...
DESCRIPTION
Normally, ranlib converts each archive to a form that the loader, ld(1), can load more rapidly. It does this by adding a table of contents called _.SYMDEF to the beginning of the archive.
The DOMAIN/IX version of ranlib is a no-op, however. This is because the libraries are already in a format that allows the loader to randomly access their constituents.
