2. Oops! I will do that!

3. Yes, you need 1.5 because I was lazy and used generic classes.

Java is pretty insistent about pushing updates at you so you might already have it.
4. What's so bad about .NET compared to Java? The runtimes are about the same size to install...

Yeah, sorry about all the trouble... I've just been wanting to get something out there. Calc is licensed under the LGPL, though, so I'm pretty sure I'd be allowed to include a Windows binary with my distribution of the templatizer, as long as I provided a link to the source code as well. (Anyone want to back me up on that? I don't feel like perusing the whole license again!

)
As for an installer, I'd have to see... I've never found a really decent installer generator, and the program doesn't require a whole lot of files to run. But I could whip up a little batch file or Java program which would copy the files to convenient locations, and maybe even put them in your PATH environment variable so you can call them from anywhere...
