+ * GAMMA: gamma launcher is much simpler than regular java launcher in that
+ * JVM is either statically linked in or it is installed in the
+ * same directory where the launcher exists, so we don't have to
+ * worry about choosing the right JVM based on command line flag, jar
+ * file and/or ergonomics. Intead of removing unused logic from source
+ * they are commented out with #ifndef GAMMA, hopefully it'll be easier
+ * to maintain this file in sync with regular JDK launcher.

+ *
+ * If JAVA_ARGS is defined, then acts as a launcher for applications. For

+ * prefixed with '-J' will be passed directly to the 'java' command.

+ * One job of the launcher is to remove command line options which the
+ * vm does not understand and will not process. These options include
+ * options which select which style of vm is run (e.g. -client and
+ * -server) as well as options which select the data model to use.
+ * Additionally, for tools which invoke an underlying vm "-J-foo"
+ * options are turned into "-foo" options to the vm. This option
+ * filtering is handled in a number of places in the launcher, some of
+ * it in machine-dependent code. In this file, the function
+ * CheckJVMType removes vm style options and TranslateApplicationArgs
+ * removes "-J" prefixes. On unix platforms, the
+ * CreateExecutionEnvironment function from the unix java_md.c file
+ * processes and removes -d<n> options. However, in case
+ * CreateExecutionEnvironment does not need to exec because
+ * LD_LIBRARY_PATH is set acceptably and the data model does not need
+ * to be changed, ParseArguments will screen out the redundant -d<n>
+ * options and prevent them from being passed to the vm; this is done
+ * by using the machine-dependent call
+ * RemovableMachineDependentOption.

+ * | aliasLine
+ * | warnLine
+ * | ignoreLine

+ * commentLine := "#" text EOL
+ * flag := "-" identifier
+ *
+ * The semantics are that when someone specifies a flag on the command line:
+ * - if the flag appears on a knownLine, then the identifier is used as
+ * the name of the directory holding the JVM library (the name of the JVM).
+ * - if the flag appears as the first flag on an aliasLine, the identifier
+ * of the second flag is used as the name of the JVM.
+ * - if the flag appears on a warnLine, the identifier is used as the
+ * name of the JVM, but a warning is generated.
+ * - if the flag appears on an ignoreLine, the identifier is recognized as the
+ * name of a JVM, but the identifier is ignored and the default vm used
+ * - if the flag appears on an errorLine, an error is generated.
+ * - if the flag appears as the first flag on a predicateLine, and
+ * the machine on which you are running passes the predicate indicated,
+ * then the identifier of the second flag is used as the name of the JVM,
+ * otherwise the identifier of the first flag is used as the name of the JVM.
+ * If no flag is given on the command line, the first vmLine of the jvm.cfg
+ * file determines the name of the JVM.
+ * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
+ * since they only make sense if someone hasn't specified the name of the
+ * JVM on the command line.
+ *
+ * The intent of the jvm.cfg file is to allow several JVM libraries to
+ * be installed in different subdirectories of a single JRE installation,
+ * for space-savings and convenience in testing.
+ * The intent is explicitly not to provide a full aliasing or predicate
