  25 # This script launches HotSpot.
  26 #
  27 # If the first parameter is either "-gdb" or "-gud", HotSpot will be
  28 # launched inside gdb. "-gud" means "open an Emacs window and run gdb
  29 # inside Emacs".
  30 #
  31 # If the first parameter is "-dbx", HotSpot will be launched inside dbx.
  32 # 
  33 # If the first parameter is "-valgrind", HotSpot will be launched
  34 # inside Valgrind (http://valgrind.kde.org) using the Memcheck skin,
  35 # and with memory leak detection enabled.  This currently (2005jan19)
  36 # requires at least Valgrind 2.3.0.  -Xmx16m will also be passed as
  37 # the first parameter to HotSpot, since lowering HotSpot's memory
  38 # consumption makes execution inside of Valgrind *a lot* faster.
