[FWTools] FWTools portable

[Matt Wilkie]

Hi Pedro,

A barebones Osgeo4W[1] install, meaning just the command line utilities, 
is portable out of the box, though the initial setup does leave a foot 
print on the host. Osgeo4w is FWTools successor.

Essentially just install as normal, using Advanced install and selecting 
only the /gdal-python/ package (a shortcut which will grab all the 
dependencies also). When that is done simply copy the C:\OSGeo4W tree to 
[usbdrive]:\OSGeo4W.

To use it on other systems just run X:\OSGeo4W\Osgeo4w.bat.

The host footprint is:
   - Start Menu and Desktop shortcuts to Osgeo4w.bat
   - possibly, some updated dll's in Windows\System32 or other PATH 
directories

The host dll's which might be touched are found in the msvcrt 
package[2]. This is generally harmless as they are standard files 
installed by many many programs. Osgeo4w only updates the system dll's 
if they are a) already present, and b) older. Otherwise they all go 
X:\Osgeo4w\bin\*.dll.

Many of the other o4w programs are portable too, though their relevant 
startup batch files might need some tweaking. Use OSGeo4W.bat and 
bin\o4w_env.bat as examples -- speaking of which, you may be able to use 
them as examples to make your already existing FWTools install portable.
