/* omshell.c
 * This is the implementation of the build-in shell output module.
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!
 *
 * shell support was initially written by bkalkbrenner 2005-09-20
 *
 * File begun on 2007-07-20 by RGerhards (extracted from syslogd.c)
 * This file is under development and has not yet arrived at being fully
 * self-contained and a real object. So far, it is mostly an excerpt
 * of the "old" message code without any modifications. However, it
 * helps to have things at the right place one we go to the meat of it.
