In either case, you will need MPW-GM to build the make-docfile utility
and to generate the doc string file DOC.

To build Emacs in the MPW Shell, simply set the directory to
...:emacs:mac: and build the target Emacs of the make file
-makefile.mpw. I.e., execute the commands
+makefile.MPW. I.e., execute the commands

prompted to save the project, navigate to same directory as the file
cw6-mcp.xml, name the project emacs-cw6.mcp, and save it there. Then
choose Project->Make. Note that this does not build the DOC file. To
do so, use MPW and build the target "Doc" in makefile.MPW.

* NOTES
-Emacs should build and run on a PowerMac running Mac OS 8.6 - 10.2.
+Emacs should build and run on a PowerMac running Mac OS 8.6 - 9.2 (but
+only tested on 9.2.2), and Mac OS X 10.1 - 10.4.
You will need around 100 MB of disk space for the source files and
intermediate files.
-It will not run on machines running Mac OS 8/9 with more than 256 MB
-of physical or virtual memory. It does not have this restriction when
-it is run under Mac OS X. But the usual 128MB buffer limit of a
-32-bit Emacs still exists.
-
-Under Mac OS 8/9, there is no support for building the LEIM directory.
-However, it can be built on Mac OS X or another platform and
-transferred to the Mac.
-
-On Mac OS 8/9, to use the same icon as when Emacs is built on Windows
-NT, define GNU_ICON in mac/src/Emacs.r. Currently Emacs uses a
-generic application icon on the Mac OS X. A better looking one is
-coming soon.
+Under Mac OS Classic, there is no support for building the LEIM
+directory. However, it can be built on Mac OS X or another platform
+and transferred to the Mac.
On Mac OS X, installing the emacs files in /usr can cause issues with
-system sofware updates possibly overwriting the distribution. If this
+system software updates possibly overwriting the distribution. If this
is a concern, as it should be in normal binary distributions, please
use /usr/local as the prefix for installation.
-Enjoy!
+Emacs supports both PowerPC and Intel-based Macintoshes. However,
+due to the unexec process that Emacs uses to dump core, it is not
+possible at this time to generate a universal binary that supports both
+architectures. In addition, Rosetta doesn't appear to work correctly
+with PowerPC builds of Emacs; you will have to recompile for Intel.
+Therefore, builds of Emacs are architecture specific.
