+ * 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 RemovableOption.

+ * Read the jvm.cfg file and fill the knownJVMs[] array.

+ * The functionality of the jvm.cfg file is subject to change without
+ * notice and the mechanism will be removed in the future.
+ *
+ * The lexical structure of the jvm.cfg file is as follows:
+ *
+ * jvmcfg := { vmLine }
+ * vmLine := knownLine
+ * | aliasLine
+ * | warnLine
+ * | ignoreLine
+ * | errorLine
+ * | predicateLine
+ * | commentLine
+ * knownLine := flag "KNOWN" EOL
+ * warnLine := flag "WARN" EOL
+ * ignoreLine := flag "IGNORE" EOL
+ * errorLine := flag "ERROR" EOL
+ * aliasLine := flag "ALIASED_TO" flag EOL
+ * predicateLine := flag "IF_SERVER_CLASS" flag EOL
+ * 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
+ * mechanism.
