1.28 +# This script launches HotSpot.
1.29 +#
1.30 +# If the first parameter is either "-gdb" or "-gud", HotSpot will be
1.31 +# launched inside gdb. "-gud" means "open an Emacs window and run gdb
1.32 +# inside Emacs".
1.33 +#
1.34 +# If the first parameter is "-dbx", HotSpot will be launched inside dbx.
1.35 +#
1.36 +# If the first parameter is "-valgrind", HotSpot will be launched
1.37 +# inside Valgrind (http://valgrind.kde.org) using the Memcheck skin,
1.38 +# and with memory leak detection enabled. This currently (2005jan19)
1.39 +# requires at least Valgrind 2.3.0. -Xmx16m will also be passed as
1.40 +# the first parameter to HotSpot, since lowering HotSpot's memory
1.41 +# consumption makes execution inside of Valgrind *a lot* faster.
