Thanks.

Fair point; I've moved both of these to comments in the file.

Fixed.

I now use lowercase "jit" throughout.

Done.

(Your proposal is superior since it avoids potentially long command
lines; but out of interest, why specifically avoid bash here?)

The jit documentation has a nested directory structure (e.g. there are 7
instances of an "index.html" within them), "$file" actually will contain
a path to a file, so we do need to have $file on the right-hand side of
the cp command.

I've added a comment to clarify that.

I'm attaching a revised patch which I hope addresses these issues;
tested (crudely) as before.

How does this look?

Thanks
