Below an example how I use this:
1) I create a postTangleScript.sh, which I want to execute after
tangling. In this script, I put all the things I want to do.
2) I set the post-tangle-hook, so that the script is executed.
3) if you want to have the name of the tangled file automatically in
your post tangle script, you can use variables (but don't ask me how to
get the name of the tangled file)

Hope this helps,

Rainer
