If you are debugging a daemon, you may want to have additional debugging information. For instance, if you are debugging the collector, you can edit COLLECTOR_DEBUG. For instance, you might do:
 {code}
-COLLECTOR_DEBUG = D_FULLDEBUG D_COMMAND:1
+COLLECTOR_DEBUG = D_CAT D_FULLDEBUG D_COMMAND:1
 {endcode}
 Note that this set up described above is rather nice for working with different versions of HTCondor. Just change the link to the release directory, and you can test a different version of HTCondor.
