ranlib - convert archives to random libraries
ranlib archive ...
Ranlib converts each archive to a form which the loader can load more
rapidly. Ranlib does this by adding a table of contents called
_.SYMDEF to the beginning of the archive. Ranlib uses ar(1) to recon-
struct the archive, so that sufficient temporary file space must be
available in the file system which contains the current directory.
ld(1), ar(1), lorder(1)
Because generation of a library by ar and randomization of the library
by ranlib are separate processes, phase errors are possible. The
loader, ld, warns when the modification date of a library is more
recent than the creation date of its dictionary; but this means that
you get the warning even if you only copy the library.
