+// The "API version" is used as a way of checking that interfaces in the
+// liboctave and libinterp libraries haven't changed in a backwardly
+// incompatible way when loading .oct files.  A better way to do that is
+// with library versioning, but not all systems support that.
+// NOTE: This macro will be removed in a future version of Octave.  If
+// you insist on checking for features using a version number, use the
+// OCTAVE_MAJOR_VERSION, OCTAVE_MINOR_VERSION, and
+// OCTAVE_PATCH_VERSION macros instead.
