Message:

Allow shebang scripts
Now a tailor script can be signed with the usual shebang notation. In
this case, it is treated as full fledged Python script: it gets executed
and it docstring become the actual configuration. This allow runtime
definition of functions that may be referenced from the various hooks

Of course, even the docstring may be computed dynamically, explicitly
assigning to the special doc variable.
