29This is the main entry point to logging. Note that the extra set of
30parentheses are required due to limitations in C89 macros.
31
32This will format a string with the current file and line number to the
33log file if logging is enabled.

35This must be called with a context object defined by one of the
36C<dIMCTX> macros in scope.
37
38This can also be called as C<mm_log((level, format, args))> in which
39case the currently active context is used and any in scope context is
40ignored.
