 # 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.
