  38 Usage: elisp-comp [--help] [--version] FILES...
  39
  40 This script byte-compiles all `.el' files listed as FILES using GNU
  41 Emacs, and put the resulting `.elc' files into the current directory,
  42 so disregarding the original directories used in `.el' arguments.
  43
  44 This script manages in such a way that all Emacs LISP files to
  45 be compiled are made visible between themselves, in the event
  46 they require or load-library one another.

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