# This script configures and builds Emacs to the subdirectory ./build .
#
# If --shared-lisp 'install_prefix' is given, lisp files will be installed to
# install_prefix/share/emacs/23.0.0.  This option must be run with 'sudo'.
#
# Otherwise (default) lisp will be installed under Emacs.app/Contents/Resources.
# It does this by configuring it to install there, and running "make install".
#
# Some setup is different for GNUstep vs. Cocoa, and it determines which one
# it's on using 'uname'.

# After it is run, Emacs can be run directly from the .app, which itself
# can be placed anywhere.

# Further C development can be done using Xcode on OS X (not tested recently),
# or by typing './remake' in the '../src' directory.  Further Lisp
# development can be done by either copying the files you modify
# into install location, or running this script again.


# Set up path and config variables.
