[CM] Make a debugger in s7?

[Iain Duncan]

Hi Bill, in s7-scm.html it says *debug.scm has various debugging aids,
including trace, break, watch, and a C-style stacktrace. The *s7* field
'debug controls when these are active, and to what extent.*

Does that mean my s7 program just needs to load debug.scm in order to use
these?

thanks
iain
