nhmall 02a48aa8cf split g into multiple structures
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.

It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.

Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.

To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.

A global variable named 'amulets', would be found in ga.
    ga.amulets
     ^ ^
A global varable named 'move', would be found in gm.
    gm.moves
     ^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
    gv.val_for_n_or_more
     ^ ^
A global variable named 'youmonst' would be found in gy.
    gy.youmonst
     ^ ^

This README provides the instructions for building the unofficial Mac
binaries using the Apple provided developer IDE named XCode.

Establish a developer team in XCode
===================================

Your first step should be to establish a developer team within XCode.
Launch XCode and open the preferences dialog (XCode Menu->Preferences).
Select the "Accounts" tab.  Add an account (usually this should just be
your apple ID account you used to setup the Mac).  After adding the account,
select the account and then add a team (usually this will be just a
personal team for Mac Development).

Obtain your developer team identifier
=====================================

Your DEVELOPMENT_TEAM can be found by opening Keychain Access
(found by Finder->Applications->Utilities).  Click on "My Certificates".
Look for your "Mac Developer" certificate.  Right click on
the certificate to open a dialog that shows certificate details.
Look for "Organizational Unit" among the details.  This ten digit value
is your development team identifier.

Create XCodeLocal.xcconfig file
===============================

Now you need to create the XCodeLocal.xcconfig file that will be used by
XCode to get your development team identifier.  Create the file in
sys/unix and add a single line such as:
DEVELOPMENT_TEAM = XXXXXXXXXX

Where XXXXXXXXXX is replaced with your development team identifier.

Open the project and build
==========================

In XCode open the project file sys/unix/NetHack.xcodeproj, select
the product NetHack and build.  The build results are placed in
~/nethackdir.
