+command.evaluate.help: For debugging purposes, you can use this to run certain
+    Python language expressions within the running engine's context, though for
+    safety reasons only a limited set of builtins are allowed, as well as
+    objects in the mudpy package namespace and the active universe object.
+    Expressions containing "__" or "lambda" are also prohobited for additional
+    safety. Everything following the word "evaluate" is assumed to be a Python
+    expression, and is passed to the eval() built-in, outputting a string
+    representation of whatever it returns. Any exceptions are caught in an
+    attempt to avoid accidentally crashing the engine. This command is mostly
+    useful for inspecting the contents of in-memory objects, for
+    example:$(eol)$(eol) evaluate universe.groups['actor'].keys()
