+
+This is the main entry point to logging. Note that the extra set of
+parentheses are required due to limitations in C89 macros.
+
+This will format a string with the current file and line number to the
+log file if logging is enabled.
+
+This must be called with a context object defined by one of the
+C<dIMCTX> macros in scope.
+
+This can also be called as C<mm_log((level, format, args))> in which
+case the currently active context is used and any in scope context is
+ignored.
