Usage: elisp-comp [--help] [--version] FILES...

This script byte-compiles all `.el' files listed as FILES using GNU
Emacs, and put the resulting `.elc' files into the current directory,
so disregarding the original directories used in `.el' arguments.

This script manages in such a way that all Emacs LISP files to
be compiled are made visible between themselves, in the event
they require or load-library one another.

Report bugs to <bug-automake@gnu.org>.
