Hi,
there is a nice little python script called "burn" (in the package of the same name). After installing it, you can set it up using "burn-configure" (accepting the default choices for most options should be fine).
You can create an iso of a directory tree and burn it with the following command:
Code:
burn -I -p /path/to/burn
If this is not exactly what you want, have a look at the burn man page: there is a very nice EXAMPLES section.
HTH,
