[Fab-user] Exceptions on tasks

[Charles Gagnon]

Sorry if this is obvious but I'm very novice at Python and Fabric.
I've researched tghe documentation I could find but could find
anything for this particular case. I have a simple fabfile which
includes a task requiring an argument:

@task
def myTask(itsargument):
    """ blah """
...

It runs fine if I do:

   fab -H host fabfile.myTask:itsargument=value

It works as I want it to. But if I omit the argument, I get a
TypeError exception:

   TypeError: myTask() takes exactly 1 argument (0 given)

Which I would like to catch and output usage(). So far, I have not
been able to do so.
