-Welcome to the MacOS port of FreePascal (FPC)
-==============================================
+The info in this file has moved to 
 
-It is considered under construction, at the moment.
+http://www.freepascal.org/wiki/index.php/Mode_MacPas
 
-Most of the programs in demo/text works.
-
-Prerequisites:
---------------
-Please note that compiling must be done on a platform
-supported by FPC, either in Darwin (MacOS X) or e g on
-Windows or Linux.
-
-MPW (or ToolServer, but the rest of the description consider doing it
-from MPW) must be installed on the target Macintosh.
-It can be downloaded from Apple Computer, see
-ftp://ftp.apple.com/developer/Tool_Chest/Core_Mac_OS_Tools/MPW_etc./
-
-Compiling on host:
-------------------
-When compiling for target MacOS, use FPC as for other
-operating systems with these options:
-
--Tmacos # target macos
--st	# dont generate executable, link on target
-
-If make is used, add OPT=-st OS_TARGET=macos (on foreign platforms
-CPU_TARGET=powerpc must also be added)
-
-Note that one must first build the RTL by issuing make in rtl/macos, with
-the above options, to be able to buld other programs. (Currently only
-system.pp and som OS independant units are available)
-
-You might also want to add option -a, then the link script will not delete
-not needed files, in particular the assembler files (*.s). This can be
-useful if there are problems with the link script and you want to rerun it.
-
-Assembling and linking on target:
----------------------------------
-In case that host and target machine is different, transfer the produced
-files, that is assembler files (*.s) and link script *_ppas, to the host.
-
-On the target, use MPW to assemble and link the output from FreePascal by
-executing the link script (which is an MPW script), with its directory
-as current directory. Unfortunatelly the link script does not have the
-proper mac file type, so this has to be fixed first e. g with
-the MPW command SetFile.
-
-Example: To build Hello World, execute:
-
-Directory HD:Projekt:FreePascal:fpc:rtl:macos
-SetFile -c 'MPS ' -t 'TEXT' system_ppas
-system_ppas	#executes the script
-Directory HD:Projekt:FreePascal:fpc:demo:text
-SetFile -c 'MPS ' -t 'TEXT' hello_ppas
-hello_ppas	#executes the script
-
-
-Note on the compiler implementation
-===================================
-
-Global variables
-----------------
-Currently all global variables are indirect, that is the entry in
-the TOC is always a pointer to data. (In the future small data items
-may be stored directly in the TOC)
-
-Thus all references to globals are via a construct like:
-lwz rX, yyy[TC](r2)  ;loads a pointer to a global into rX
-
-Debugging
-----------
--g is considered under construction.
-
-When -g has been fixed, some debugging should be possible in
-Power Mac Debugger 2.1, can be downloaded from Apple,
-ftp://ftp.apple.com/developer/Tool_Chest/Core_Mac_OS_Tools
-/MPW_etc./Debuggers/Power_Mac_Debugger.sit.hqx
-
-
-It should be possible to see source code
-but it will not be possible to examine variables.
-One can of course examine registers, especially
-at entry and exit point where the parameter lists is stored
-in registers, according to the calling conventions.
-
-A suggestion is to do the main debugging in GDB in the Darwin version of the
-program.
