bltdebug(3) print Tcl commands before execution

SYNOPSIS

bltdebug ?level?




DESCRIPTION

The bltdebug command is a simple tracing facility for Tcl commands. Each command line is printed before it is executed on standard error. The output consists of the command line both before and after substitutions have occurred. Level indicates at what level to stop tracing commands. If level is 0, no tracing is performed. This is the default. If no level argument is given, the current level is printed.
