/**
* Defines the implementation of the
* {@linkplain javax.tools.ToolProvider#getSystemJavaCompiler system Java compiler}
* and its command line equivalent, <em>{@index javac javac tool}</em>,
* as well as <em>{@index javah javah tool}</em>.
*
* <h2 style="font-family:'DejaVu Sans Mono', monospace; font-style:italic">javac</h2>
*
* <p>
* This module provides the equivalent of command-line access to <em>javac</em>
* via the {@link java.util.spi.ToolProvider ToolProvider} and
* {@link javax.tools.Tool} service provider interfaces (SPIs),
* and more flexible access via the {@link javax.tools.JavaCompiler JavaCompiler}
* SPI.</p>
*
* <p> Instances of the tools can be obtained by calling
* {@link java.util.spi.ToolProvider#findFirst ToolProvider.findFirst}
* or the {@linkplain java.util.ServiceLoader service loader} with the name
* {@code "javac"}.
*
* <p>
* In addition, instances of {@link javax.tools.JavaCompiler.CompilationTask}
* obtained from {@linkplain javax.tools.JavaCompiler JavaCompiler} can be
* downcast to {@link com.sun.source.util.JavacTask JavacTask} for access to
* lower level aspects of <em>javac</em>, such as the
* {@link com.sun.source.tree Abstract Syntax Tree} (AST).</p>
*
* <p>This module uses the {@link java.nio.file.spi.FileSystemProvider
* FileSystemProvider} API to locate file system providers. In particular,
* this means that a jar file system provider, such as that in the
* {@code jdk.zipfs} module, must be available if the compiler is to be able
* to read JAR files.
*
* <h2 style="font-family:'DejaVu Sans Mono', monospace; font-style:italic">javah</h2>
*
* <p>
* <em>javah</em> only exists as a command line tool, and does not provide any
* direct API. As of JDK 9, it has been deprecated.
* Use the {@code -h} option in <em>javac</em> instead.</p>
