//
//  For ease of debugging the SPMgr, all the debug support functions have
//  been stuck here.  Basically, we read info from win.ini, since that allows
//  us to configure the debug level via a text file (and DOS, for example).
//
//  Format is:
//
//  win.ini
//
//  [SPMgr]
//      DebugFlags=<Flag>[<,Flag>]*
//      Package=<int>
//      BreakFlags=<BreakFlag>[<,BreakFlags>]*
//
//  WHERE:
//      Flag is one of the following:
//          Error, Warning, Trace, Verbose, BreakOnError, Helpers,
//          RefMon, Locator, WAPI, Init, Audit, Db, Lsa
//
//      Package is the name of the dll implementing the package, e.g.
//          NTLM=3
//
//      BreakFlags will cause SPMgr to break, if BreakOnError is set in
//      DebugFlags:
//          InitBegin, InitEnd, Connect, Exception, Problem, Load
//
//

// Debugging support functions.

// These two functions do not exist in Non-Debug builds.  They are wrappers
// to the commnot functions (maybe I should get rid of that as well...)
// that echo the message to a log file.
