  5.  
  6. This is multi-line data, executed line by line in their list orders. The
  7. restrictions only affect resource modules, but not administration modules.
  8. Lines starting with a `<tt>#</tt>' are comments.
  9. <p>
  10. Each line is of the format <tt>[access conditions]:[host conditions]</tt>.
  11. <p>
  12. the access conditions is a list of words, which will be ANDed. The available
  13. words are listed in the following table. Each word can be prefexed with
  14. <tt>non</tt> to reverse its logical meaning.
  15. <p><center><table border=2>
  16. <tr><th>word<th>meaning
  17. <tr><td>class<td>The connection is within a virtual class.
  18. <tr><td>com<td>The requested module is under the com/ subtree.
  19. <tr><td>document<td>The requested module is a document. (not yet available)
  20. <tr><td>exercise<td>The requested module is an exercise.
  21. <tr><td>hint<td>The request is for hint.
  22. <tr><td>local<td>The requested module is under the local/ subtree.
  23. <tr><td>recreation<td>The requested module is a recreation.
  24. <tr><td>tool<td>The requested module is a tool.
  25. </table></center> <p>
  26.  
  27. The host conditions can be any host definition, eventually plus time
  28. definition as for any worksheets. If the first character of the host
  29. conditions is ``<tt>!</tt>'', then the host/time meeting the conditions will
  30. be refused access (for the resources meeting the access conditions).
  31. Otherwise they will be granted access, and subsequent lines in the
  32. restriction definition will be ignored for those meeting the conditions.
