The bltdebug command is a simple tracing facility for Tcl
commands. Each command line is printed before it is exe
cuted on standard error. The output consists of the com
mand 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.
