+GNU Octave strives to be among the very best numerical tools available.
+While compatibility with Matlab is one of many strong features of Octave,
+we have not achieved 100% compatibility.
+If you are reading this page, it is most likely because you attempted to
+use a function that is part of core Matlab, but has yet to be implemented
+in Octave.
+
+There can be several reasons for the given function not to exist in Octave:
+
+- The function may exist in [Octave-Forge][1], but has not yet been adopted
+  as a part of the core Octave distribution.  You can try to look for your
+  function in the [alphabetical list of functions][2] at the Octave-Forge
+  web site to see if it is available in some package.
+
+- The function may be new to Matlab.  It is possible that the Octave
+  community simply does not know it exists.  Should this be the case,
+  feel free to open a feature request in the [Octave bug tracker][3].
+
+The Octave community consists of volunteers working in their spare time.
+As a result, development might sometimes not be fast enough for your needs.
+If you have a feature request for Octave, the best way to ensure that your
+suggested improvement gets incorporated is either to implement the feature
+yourself or to pay somebody to do it for you.
+If you are interested in funding work on Octave, please check out
+the [resources for developers][4].
