#!/bin/sh

#### make-package: create a Mac OS X package for use by the installer.
#### The installer will place the Emacs OSX application in
#### /Application/Emacs and the rest of emacs in the usual unix places
#### under /usr/local or some other location if specified as the first
#### argument. The disc image will be in the file EmacsInstaller.dmg.
####
#### Upon installation, this will leave two versions of emacs on the
#### computer, 20.7 and 21.1.
####
#### Examples:
#### ./make-package
####     Will create an installer that will place the emacs support
####     files inside /usr/local.
#### ./make-package /usr
####     Will create an installer that will place the emacs support
####     files inside /usr.  This will replace the default version of
####     emacs included with Mac OS X.

\`make-package' generates a Mac OS X installer package from an Emacs 
distribution.  By default, this first runs ./configure on the emacs 
directory.  Then make install to create the emacs distribution.  
Then some mac-specific commands to generate the required information 
for the mac package.  The installer will, by default, create a
Carbon application called Emacs in the /Applications directory, and 

Usage: $0 [OPTION]

Options:
  -h, --help              display this help and exit
      --prefix=DIR        Set install location for the Mac OS X package
                          of the emacs related file.  By default /usr/local
      --no-conf           Do not run the configure script before running
                          make install.
      --without-app       Do not create the Emacs application bundle
      --with-x            Setup the install to use X Windows for its 
                          windowed display, instead of carbon.  Implies
                          --without-app.
