[zeromq-dev] Adding new tests to Malamute

[Pieter Hintjens]

The best way to understand what's going on is to look at the code for
mlm_client_content () and possibly debug by adding printfs as it runs.
This is really educational and will help you use Malamute better.

Please do read & follow coding style on all patches, space before '('
and noNamesLikeThis.

Cheers :)
Pieter
