Charlie Sharpsteen 7912feb5c6 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!

caveats = <<-EOS
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.
