While many of us have been using FWTools on USB memory sticks, I noticed that there is now a script on the GDAL website that allows you to use FWTools on your USB Stick without having to install anything.
setfw_portable.cmd allows one to use fwtools for windows from a usb drive without installing anything on the host computer. It is non-invasive and won’t make any changes to the system registry or windows system directories or anything like that.
Now it was possible to do this without the script, but it sure does simplify it.
