copy_transform(transform);
- transform - input Transform object
The copy_transform command generates a complete copy of the
provided transform.
slsh> cr = read_file("evt2.fits");
slsh> trans = get_transform(cr, "MSC");
slsh> t2 = copy_transform(trans);
slsh> py_call(t2.print_parameter_list);

Copy the "MSC" transform from the file evt2.fits to "t2".
The "py_call" command is used to call a Python command
from slsh because there isn't a method to retrieve
low-level functions in S-Lang.
