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.
