! 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.
