NAME
       SableVM - manual	page for SableVM - free	(LGPL) Java Virtual Machine

SYNOPSIS
       sablevm [OPTION]... CLASSNAME [ARGUMENT]...

DESCRIPTION
       NOTE: sablevm command is	NOT command-line compatible with the java com-
       mand.  The sablevm command uses GNU style of  parameters,  and  ignores
       the  environmental  variables  often used by Java programs, like	CLASS-
       PATH.  If this is not what you want you	should	look  at  java-sablevm
       command which is	meant to be command-line compatible with the java com-
       mand.

       -c, --classpath="PATH"
	      set class	path

       -p, --property="NAME=VALUE"
	      set system property

       -v, --verbose
	      enable all verbose options

       -q, --quiet
	      disable all verbose options

       -s, --verbose-class
	      enable verbose class loading

       -S, --no-verbose-class
	      disable verbose class loading

       -g, --verbose-gc
	      enable verbose garbage collection

       -G, --no-verbose-gc
	      disable verbose garbage collection

       -j, --verbose-jni
	      enable verbose JNI

       -J, --no-verbose-jni
	      disable verbose JNI

       -y, --copyright
	      display copyright

       -Y, --no-copyright
	      do not display copyright

       -L, --license
	      display license information and exit

       -V, --version
	      display version information and exit

   Help	options:
       -?, --help
	      Show this	help message

       --usage
	      Display brief usage message

AUXILIARY PROPERTIES
       It is possible to place multiple	elements on boot classpath. Each  ele-
       ment  may  be  either  a	top directory of class tree or a .jar (or zip)
       file.  SableVM offers flexible setup of boot class path thru  usage  of
       the following properties.

       sablevm.boot.class.path
	      changes boot classpath

       sablevm.boot.class.path.prepend
	      prepends entries to default or set boot classpath

       sablevm.boot.class.path.append
	      appends entries to default or set	boot classpath

       sablevm.boot.library.path
	      changes native libraries patch which are used by boot classpath

       (WARNING: the two last properties above are very	fragile; expect
	      cannot create vm messages	if you use them	in a wrong way.

MEMORY USAGE CONTROL PROPERTIES
       There  exist a number of	properties that	can be used to tune memory us-
       age of SableVM. Normally	it is NOT  needed  to  use  any	 of  them,  as
       SableVM	will  take care	of allocating as much memory, as your applica-
       tion needs and of freeing the memory when it  is	 not  needed  anymore.
       Still, there are	some situations	when you want to tune or limit maximum
       memory usage.

       The general pattern of available	memory controlling properties is:

       sablevm.[stack,classloader.heap].size.[min,max,increment]

       which tranlates into the	following set of available properties:

       sablevm.stack.size.min

       sablevm.stack.size.max

       sablevm.stack.size.increment

       sablevm.heap.size.min

       sablevm.heap.size.max

       sablevm.heap.size.increment

       sablevm.classloader.size.min

       sablevm.classloader.size.max

       sablevm.classloader.size.increment

	      These properties allow for control over java stack,  java	 heap,
	      and java class loader.

	      Meaning of the min, max, increment suffixes is the following:

	      ...min initial size in bytes,

	      ...max maximal size in bytes (hard limit); 0 means "no limit",

	      ...increment  step  by which the amount of memory	is incremented
	      when needed, up to the limit specified in	max, if	any;  0	 means
	      "fixed size" (no changes allowed,	min is used).

DEBUGGING PROPERTIES
       sablevm.verbose.methods
	      when  operating  on  a binary compiled with debugging features -
	      setting this property to true outputs names of every method that
	      is to be executed

       sablevm.verbose.instructions
	      when  operating  on  a binary compiled with debugging features -
	      setting this property to true outputs names of every instruction
	      that is to be executed (WARNING: expect flood!!!)

       sablevm.verbose.synchronization
	      when  operating  on  a binary compiled with debugging features -
	      setting this property to true causes SableVM  to	dump  a	 stack
	      trace on every locking contention	and on fat lock	acquisition.
