The 'schule' bundle was built to provide packages and commands
that could be useful for documents in German schools. At the
moment its main focus lies on documents for informatics as a
school subject. An extension for physics is currently in
progress. Extensions for other subjects are welcome. For the
time being, the whole package splits up into individual
packages for informatics (including syntax diagrams, Nassi-
Shneiderman diagrams, sequence diagrams, object diagrams, and
class diagrams) as well as classes for written exams (tests,
quizzes, teaching observations, information sheets, worksheets,
and answer keys).
