DESCRIPTION

       The idebug command provides an interactive debugging environment for procedures via TkCon.
       You can place idebug break commands into your procedure to create  breakpoints.   It  will
       pop  up  the  TkCon  console  and put you into a "debugging" mode.  The body, show & trace
       methods are intended for internal use only.  This procedure works  for  minimal  debugging
       sessions.  Comments are encouraged.

       idebug body ?level?
              Prints  out  the body of the command (if it is a procedure) at the specified level.
              level defaults to the current level.

       idebug break ?id?
              Creates a breakpoint within a procedure.  This will only trigger if  idebug  is  on
              and the id matches the pattern.  If so, TkCon will pop to the front with the prompt
              changed to an idebug prompt.  You are given the basic ability to observe  the  call
              stack  an  query/set  variables  or  execute Tcl commands at any level.  A separate
              history is maintained in debugging mode.  To see the special commands available  at
              the debug prompt, type ? and hit return.

       idebug {echo ?id?} ?args?
              Behaves  just  like  echo, but only triggers when idebug is on.  You can specify an
              optional id to further restrict triggering.  If no id is specified, it defaults  to
              the name of the command in which the call was made.

       idebug id ?id?
              Query  or  set the idebug id.  This id is used by other idebug methods to determine
              if they should trigger or not.  The idebug id can be a glob pattern and defaults to
              *.

       idebug off
              Turns idebug off.

       idebug on ?id?
              Turns idebug on.  If id is specified, it sets the id to it.

       idebug {puts ?id?} args
              Behaves  just  like  puts, but only triggers when idebug is on.  You can specify an
              optional id to further restrict triggering.  If no id is specified, it defaults  to
              the name of the command in which the call was made.

       idebug show type ?level? ?VERBOSE?
              type  must  be  one  of  vars,  locals  or  globals.   This  method will output the
              variables/locals/globals present in a particular level.  If VERBOSE is added,  then
              it  actually  dumps  out  the values as well.  level defaults to the level in which
              this method was called.

       idebug trace ?level?
              Prints out the stack trace from the specified level up to  the  top  level.   level
              defaults to the current level.
