+  Add an assertion. The command is followed by an expression, an action
+  specifier and a message that is output in case the assertion fails. The
+  action specifier may be one of <tt/warning/ or <tt/error/. The assertion

+
+  The example assertion will check that the current location is at $8000,
+  when the output file is written, and abort with an error if this is not
+  the case. More complex expressions are possible. The action specifier
+  <tt/warning/ outputs a warning, while the <tt/error/ specifier outputs
