| * instance, the JDK command line tools such as javac and javadoc (see |
| * makefiles for more details) are built with this program. Any arguments |
| * 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. The CreateExecutionEnvironment function processes |
| * and removes -d<n> options. On unix, there is a possibility that the running |
| * data model may not match to the desired data model, in this case an exec is |
| * required to start the desired model. If the data models match, then |
| * ParseArguments will remove the -d<n> flags. If the data models do not match |
| * the CreateExecutionEnviroment will remove the -d<n> flags. |

| * 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. |
