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! Signed-off-by: Adam Vandenberg <flangy@gmail.com>

def caveats

|
||||
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.
