# This is a script to start Erlang/OTP for debugging. PATH is set to
# include this script so if slave nodes are started they will use this
# script as well.
#
#  usage:  cerl [ OPTIONS ] [ ARGS ]
#
#  The OPTIONS are
#
#   -rootdir $MYROOTDIR
#               Run an installed emulator built from this source
#   -debug      Run debug compiled emulator
#   -gdb        Run the debug compiled emulator in emacs and gdb.
#               You have to start beam in gdb using "run".
#   -break F    Run the debug compiled emulator in emacs and gdb and set break.
#               The session is started, i.e. "run" is already don for you.
#   -xxgdb      FIXME currently disabled
#   -purify     Run emulator compiled for purify
#   -quantify   Run emulator compiled for quantify
#   -purecov    Run emulator compiled for purecov
#   -gcov       Run emulator compiled for gcov
#   -valgrind   Run emulator compiled for valgrind
#   -lcnt	Run emulator compiled for lock counting
#   -nox        Unset the DISPLAY variable to disable us of X Windows
#
# FIXME For GDB you can also set the break point using "-break FUNCTION".
# FIXME For GDB you can also point out your own .gdbini......
