I wrote all of these tools for my own use, when I needed a particular tool for a particular task at a particular time.
I'm making them available, some with source code, in the hope that you might also find them useful.
There are no guarantees that any of these tools will work for you, and you use them entirely at your own risk. I accept no responsiblity for any damage that may be caused by their use.
