You may supply at least one format on the command line.  Recognized formats
are:
    binaries    for binaries
    source      for source code
The default is both source and binaries.

You may also supply actions.  Recognized actions are:
    extract     read the appropriate files from tape
    fixincludes build a directory of corrected header files for comp-tools 
    test        run a very brief verification of your installation
Default actions are extract, fixincludes, and test, although fixincludes is not
necessary for emacs.

There are two other options:
    -tape=DEVICE   asks Install to read the necessary files from DEVICE. The
                   default DEVICE is ||DEVdflt||, the ||TAPdflt||, cartridge tape
                   drive on most ||HOSTstr||s.
    -installdir=DIRECTORY       asks Install to install files into DIRECTORY.
                                The default DIRECTORY is ${INSTALLDIR_DEFAULT}.
