* Utility methods and classes for writing jtreg tests for

*
* <p>There is support for common file operations similar to
* shell commands like cat, cp, diff, mv, rm, grep.
*
* <p>There is also support for invoking various tools, like
* javac, javah, javap, jar, java and other JDK tools.
*

* to represent filenames. On all platforms on which JDK is supported,
* "/" is a legal filename component separator. In particular, even
* on Windows, where the official file separator is "\", "/" is a legal
* alternative. It is therefore recommended that any client code using
* strings to specify filenames should use "/".
