/* omtesting.c
*
* This module is a testing aid. It is not meant to be used in production. I have
* initially written it to introduce delays of custom length to action processing.
* This is needed for development of new message queueing methods. However, I think
* there are other uses for this module. For example, I can envision that it is a good
* thing to have an output module that requests a retry on every "n"th invocation
* and such things. I implement only what I need. But should further testing needs
* arise, it makes much sense to add them here.
*
* This module will become part of the CVS and the rsyslog project because I think
* it is a generally useful debugging, testing and development aid for everyone
* involved with rsyslog.
*
* CURRENT SUPPORTED COMMANDS:
*
* :omtesting:sleep <seconds> <milliseconds>
*
* Must be specified exactly as above. Keep in mind milliseconds are a millionth
* of a second!
*
* NOTE: read comments in module-template.h to understand how this file
* works!
