    2: 
    3: \begin{itemize}
    4: \item \textbf{display}\index{display}: The intervening perl script is evaluated
    5: in the safe space and the return value of the script replaces the
    6: entire tag.
    7: \item \textbf{import}\index{import}: Causes the parse to read in the file
    8: named in the body of the tag and parse it as if the entire text of
    9: the file had existed at location of the tag.
   10: \item \textbf{parserlib}\index{parserlib}: the enclosed filename contains
   11: definitions for new tags.
   12: \item \textbf{script}\index{script}: If the attribute \textbf{type} is
   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
   15: is ignored. 
   16: \item \textbf{scriptlib}\index{scriptlib}: The enclosed filename contains
   17: perl code to run in the safe space.
   18: \item \textbf{block}\index{block}: Has a required argument \textbf{condition}
   19: that is evaluated. If the condition is true everything inside the
   20: tag is evaluated, otherwise everything inside the block tag is skipped.
   21: \item \textbf{notsolved}\index{notsolved}: Everything inside the tag is
   22: skipped if the problem is {}``solved''.
   23: \item \textbf{postanswerdate}\index{postanswerdate}: Everything inside
   24: the tag is skipped if the problem is before the answer date.
   25: \item \textbf{preduedate}\index{preduedate}: Everything inside the tag
   26: is skipped if the problem is after the due date 
   27: \item \textbf{randomlist}\index{randomlist}: The enclosed tags are parsed
   28: in a stable random order. The optional attribute \textbf{show} restricts
   29: the number of tags inside that are actually parsed to no more than
   30: \textbf{show}.
   31: \item \textbf{solved}\index{solved}: Everything inside the tag is skipped
   32: if the problem is {}``not solved''.
   33: \item \textbf{while}\index{while}: Implements a while loop. The required
   34: attribute \textbf{condition} is a perl scriptlet that when evaluated
   35: results in a true or false value. On true the entirety of the text
   36: between the whiles is parsed. The condition is tested again, etc.
   37: If false it goes to the next tag.
