/* This is no longer run directly. See runconstructor.sh

 *
 *
 * This program tests the URL parser in the URL constructor. It
 * tries to construct a variety of valid URLs with a given context
 * (which may be null) and a variety of specs. It then compares the
 * result with an expected value.
 *
 * It expects that a data file named "urls" be available in the
 * current directory, from which it will get its testing data. The
 * format of the file is:
 *
 * URL: null
 * spec: jar:http://www.foo.com/dir1/jar.jar!/
 * expected: jar:http://www.foo.com/dir1/jar.jar!/
 *
 * where URL is the context, spec is the spec and expected is the
 * expected result. The first : must be followed by a space. Each test
 * entry should be followed by a blank line.
