% etp-help
% 
% Same as "help etp-help"
% 
% 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-disasm,
%   etp-msgq, etpf-msgq, 
%   etp-stacktrace, etp-stackdump, etpf-stackdump, etp-dictdump
%   etp-process-info, etp-process-memory-info
%   etp-port-info, etp-port-state, etp-port-sched-flags
%   etp-heapdump, etp-offheapdump, etpf-offheapdump,
%   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
%
% System inspection
%   etp-system-info, etp-schedulers, etp-process, etp-ports, etp-lc-dump,
%   etp-migration-info, etp-processes-memory,
%   etp-compile-info, etp-config-h-info
%
% Platform specific (when gdb fails you)
%   etp-ppc-stacktrace
%
% 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.
