= GRASS GIS =

Version: 6.4.0RC2

== User Notes ==

 * A command line and GUI desktop raster/vector GIS system.
 * http://grass.osgeo.org/
 * Details on WinGRASS at: http://grass.osgeo.org/wiki/WinGRASS_Current_Status
 * Current packaging should be considered a preliminary proof-of-concept.
 * Default install includes only the curses interfaces.  You can install the wxpython and/or tcltk package to get the other GUI interfaces.

Installation:
 * OSGeo4W has two modes - express and advanced.
   * "Express" gives you a short list of suggested packages to select from which have been widely tested. 
   *"Advanced" gives a long detailed list of packages and subpackages including development versions and so forth.
 * For the moment GRASS is available in the "advanced" install. After a period of testing it may be moved to the "express" section.

The application can be run through:
 * its executable ''osgeo4w''\apps\grass-6.4.X\bin\grass64.bat
 * a desktop shortcut
 * a menu shortcut
 * on the osgeo4w shell through the grass64.bat


== Packager Notes ==

 * Compile guide used: http://www.webalice.it/marco.pasetti/grass/BuildFromSource.html (requires updates, better move here)
 * Steps:
  * compile GRASS in a way that it fits in the OSGeo4W directory hierarchy
  * package in a tar.bz2 file
  * write/update "setup.hint" which describes the package and defines the dependencies on other OSGeo4W packages
  * if needed, write/update "etc/postinstall/$paketname.bat"  which is executed after extraction of the package during installation to define menu stuff and link on user desktop.
 * Depends on the MSYS package for command line operations, because GRASS 6 uses unix shell scripts (GRASS 7 uses Python)
 * WinGRASS is built with MSYS/MinGW.  The libraries used to link to the VC++ built GDAL & friends is in the mingw-libs package.
 * There is also a grass-vc package, that contains the VC++ built GRASS libraries.  These are used in the Quantum GIS GRASS plugin.
 * Release tree: http://download.osgeo.org/osgeo4w/release/grass/ (the installer selects the package with highest version number)
 * Maintainer is JuergenFischer (seeking new package maintainer)
