# This script launches HotSpot.
#
# If the first parameter is either "-gdb" or "-gud", HotSpot will be
# launched inside gdb. "-gud" means "open an Emacs window and run gdb
# inside Emacs".
#
# If the first parameter is "-dbx", HotSpot will be launched inside dbx.
#
# If the first parameter is "-valgrind", HotSpot will be launched
# inside Valgrind (http://valgrind.kde.org) using the Memcheck skin,
# and with memory leak detection enabled.  This currently (2005jan19)
# requires at least Valgrind 2.3.0.  -Xmx16m will also be passed as
# the first parameter to HotSpot, since lowering HotSpot's memory
# consumption makes execution inside of Valgrind *a lot* faster.
