    Defines a set of GLOBUS_SH_ variables, then sources a user script.
    The user script is a local file, or can be referred to with a GASS
    URL.

    Additional arguments "args ..." are passed on to the user script.

    Options:
        -help        Shows help and exits
        -usage       Shows help and exits
        -version     Shows version and exits
        -list (-l)   Lists the defined GLOBUS_ variables and exits
        -exec (-e)   Commands are read from the argument line 

    For user script examples, see the documentation at www.globus.org
