+% Emulator Toolbox for Pathologists
+% - GDB command toolbox for analyzing core dumps from the
+% Erlang emulator (BEAM).
+% 
+% Should work for 32-bit erts-5.2/R9B, ...
+% 
+% The commands are prefixed with:
+%   etp:  Acronym for erts-term-print
+%   etpf: Acronym for erts-term-print-flat
+% 
+% User commands (these have help themselves):
+% 
+% Most useful:
+%   etp, etpf
+% 
+% Useful for doing step-by-step traversal of lists and tuples after 
+% calling the toplevel command etpf:
+%   etpf-cons, etpf-boxed, 
+% 
+% Special commands for not really terms:
+%   etp-mfa, etp-cp, 
+%   etp-msgq, etpf-msgq, 
+%   etp-stacktrace, etp-stackdump, etpf-stackdump, etp-dictdump
+%   etp-offheapdump, etpf-offheapdump,
+%   etp-print-procs, etp-search-heaps, etp-search-alloc,
+%   etp-ets-tables, etp-ets-tabledump
+%
+% Complex commands that use the Erlang support module.
+%   etp-overlapped-heaps, etp-chart, etp-chart-start, etp-chart-end
+% 
+% Erlang support module handling commands:
+%   etp-run
+%
+% Parameter handling commands:
+%   etp-show, etp-set-max-depth, etp-set-max-string-length
+% 
+% Other commands you may find in this toolbox are suffixed -1, -2, ...
+% and are internal; not for the console user.
+% 
+% The Erlang support module requires `erl' and `erlc' in the path.
+% The compiled "erl_commands.beam" file is stored in the current
+% working directory, so it is thereby in the search path of `erl'.
+% 
+% These are just helpful commands when analyzing core dumps, but
+% you will not get away without knowing the gory details of the
+% tag bits. Do not forget about the e.g p, p/x, x and x/4x commands.
+%
+% Execution speed of user defined gdb commands is not lightning fast.
+% It may well take half a minute to dump a complex term with the default
+% max depth values on our old Sparc Ultra-10's.
+%
+% To use the Erlang support module, the environment variable ROOTDIR
+% must be set to the toplevel installation directory of Erlang/OTP,
+% so the etp-commands file becomes:
+%     $ROOTDIR/erts/etc/unix/etp-commands
+% Also, erl and erlc must be in the path.
