+% 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-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.

+% 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.
