   4 Overrides are specific permissions designed to override a
   5 role in a specific context, allowing you to "tweak" your
   6 permissions as required.

  10 For example, if users with the role Student in your course
  11 can usually start new discussions in forums, but there is
  12 one particular forum for which you want to restrict that
  13 capability, then you can set an override that PREVENTS
  14 the capability for Students to "Start new discussions".

  18 Overrides can also be used to "open up" areas of your
  19 site and courses to give users extra permissions where
  20 it makes sense.  For example, you may want to experiment
  21 giving Students the ability to grade some assignments.

  25 The interface is similar to the one for defining roles,
  26 except sometimes only relevant capabilities are shown,
  27 and you will also see some capabilities highlighted to
  28 show you what the permission for that role would be
  29 WITHOUT any override active (ie when your override is
  30 set to INHERIT).
