 # 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.
