This section controls the debugging message level for the various wacs modules and applications, making it possible to increase the amount of diagnostic output selectively to aid in debugging code or to provide information for putting in useful bug reports. At it's simplest, this section would read:

 <debug>
  <global>4</global>
 </debug>

This will set the global debug level accordingly (once the read_conf routine has been executed by the application of course). For more fine-grained control, the debug level in modules can be specified with module_wacs or for an application with app_wacsimport. That is module_ and then it's name in lower case for modules, and app_ followed by the application name (again in lower case) for applications; tool_ for command line tools, and util_ for programs normally run by other things (ie the database populators). Thus if you were working on code for wacsimport, you might choose to make this section read:

 <debug>
  <global>0</global>
  <module_wacs>1</module_wacs>
  <app_wacsimport>5</app_wacsimport>
 </debug>

These settings would provide some basic extra debugging for the wacs module (key pathnames, etc) and then pretty extreme output for the wacsimport application.
