3.2 Debugger

Distel includes a front-end to the Erlang debugger, using the same backend as the standard Tk-based OTP debugger. The Distel debugger has three parts: commands in Erlang source buffers for interpreting modules and configuring breakpoints, a “Monitor” buffer listing processes running interpreted code, and one “Attach” buffer for each process that is being single-stepped. Note that none of this will work unless the modules are compiled with the “+debug_info” switch to erlc.
