Debugger:
http://www.erlang.org/doc/doc-5.5.1/lib/debugger-3.1/doc/html/part_frame.html
http://www.erlang.org/doc/doc-5.5.1/lib/debugger-3.1/doc/html/index.html

Erlang offers a very powerful tracing facility.  In fact, once you are 
accustomed to it, you will rarely need to use a debugger.

The dbg tracing docs are here:
http://www.erlang.org/doc/doc-5.5.1/lib/runtime_tools-1.6/doc/html/dbg.html

Yet, the example of dbg is documented in a rather non-intuitive place 
(scroll closer to the middle of the page):
http://www.erlang.org/doc/doc-5.5.1/lib/stdlib-1.14.1/doc/html/ms_transform.html

The link below (at the bottom of the page) has an extension of the 
Erlang shell that simplifies usage of tracing facility:
