        !            13: set to {}``loncapa/perl'' the enclosed data is a perl script which
        !            14: is evaluated inside the perl Safe space. The return value of the script

        !            19: that is evaluated. If the condition is true everything inside the

        !            28: in a stable random order. The optional attribute \textbf{show} restricts
