New formula for GRASS GIS

The Geographic Resources Analysis Support System (GRASS) is one of the oldest,
most fully-featured Geographic Information Systems (GIS).  It happens to be open
source too!

+GRASS is currently in a transition period with respect to GUI support.  The old
+Tcl/Tk GUI cannot be built using the version of Tcl/Tk provided by OS X.  This
+has the unfortunate consquence of disabling the NVIZ visualization system.  A
+keg-only Tcl/Tk brew or some deep hackery of the GRASS source may be possible
+ways to get around this around this.
+
+Tcl/Tk will eventually be depreciated in GRASS 7 and this version has been built
+to support the newer wxPython based GUI.  However, there is a problem as
+wxWidgets does not compile as a 64 bit library on OS X which affects Snow
+Leopard users.  In order to remedy this, the GRASS startup script:
+
+    #{prefix}/grass-6.4.0/etc/Init.sh
+
+has been modified to use the OS X system Python and to start it in 32 bit mode.

+Patch to ensure 32 bit system python is used for wxWidgets
