The package provides the means to create exercises or questions
and their corresponding solutions. The questions may be divided
into classes and/or topics and may be printed selectively. Meta-
data to questions can be added and recovered. The solutions may
be printed where they are, or collected and printed at a later
point in the document all together, section-wise or selectively
by ID. The package provides the means to selectively include
questions from an external file, and to control the style of
headings of both questions and solutions.
