+/**
+ * Base class for initialization of components expecting messages,
+ * options, files/paths, and source locations (resolved files),
+ * and potentially containing child Spec.
+ * <p>
+ * <u>initialization</u>: This defines bean/xml setters for all.
+ * This converts String to IMessage using
+ * {@link MessageUtil#readMessage(String)}
+ * and String to ISourceLocation using 
+ * {@link BridgeUtil#makeSourceLocation(input)}.
+ * See those APIs for input form and limitations.
+ * A Spec also accepts (or rejects) runtime configuration from a parent
+ * in {@link adoptParentValues(RT, IMessageHandler)}.  
+ * Since some children Spec may balk but this parent Spec continue,
+ * use {@link getChildren()} to get the full list of children Spec,
+ * but {@link getWorkingChildren()} to get the list of children that
+ * are not being skipped in accordance with runtime configuration.
+ * <p> 
+ * <u>subclassing</u>: subclasses wishing other than
+ * the default behavior for reading String input should override the
+ * corresponding (bean) setter.  They can also override the 
+ * add{foo} methods to get notice or modify objects constructed
+ * from the input.
+ * <p>
+ * <u>bean properties</u>: because this is designed to work
+ * by standard Java bean introspection, take care to follow
+ * bean rules when adding methods.   In particular, a property
+ * is illegal if the setter takes a different type than the
+ * getter returns.  That means, e.g., that all List and array[] getters
+ * should be named "get{property}[List|Array]".  Otherwise 
+ * the XML readers will silently fail to set the property
+ * (perhaps with trace information that the property had
+ * no write method or was read-only).
+ * <p>
+ * <u>Coordination with writers</u>: because this reads the contents
+ * of values written by IXmlWritable, they should ensure their
+ * values are readable.  When flattening and unflattening
+ * lists, the convention is to use the {un}flattenList(..) methods
+ * in XMLWriter.
+ * @see XMLWriter@unflattenList(String)
+ * @see XMLWriter@flattenList(List)

+/** 
+ * Check input and implement defaults.
+ * This handles failure messaging and collecting temp directories
+ * for later cleanup.
+ * The default behavior is to send a fail message to the message
+ * handler.  Clients may instead:
+ * <li>Toggle abortOnException to throw AbortException on failure</li>
+ * <li>push their own message handler to redirect messages
+ *     (pop to remove if any pushed)</li>
+ * <li>subclass this to reimplement <code>fail(String)</code>
+ * <p>
+ * A component given this to do validation should
+ * not change the reporting scheme established by the caller,
+ * so the caller may lock and unlock the error handling policy.
+ * When the policy is locked, this silently ignores attempts
+ * to toggle exceptions, or delete temporary files. 
+ * XXX callers cannot prevent others from pushing other error handlers.

+ * <p>
+ * This manages baseline IRun status reporting: 
+ * any throwables are caught and reported, and
+ * the status is started before running and 
+ * (if not already completed) completed after.
+ * <p>
+ * This runs any IRunListeners specified directly in the 
+ * run*(..., IRunListener) methods
+ * as well as any specified indirectly by registering listeners per-type
+ * in {@link registerListener(Class, IRunListener)} 
+ * <p>
+ * For correct handling of nested runs, this sets up
+ * status parent/child relationships.
+ * It uses the child result object supplied directly in the
+ * runChild(..., IRunStatus childStatus,..) methods,
+ * or (if that is null) one obtained from the child IRun itself, 
+ * or (if that is null) a generic IRunStatus.  
+ * <p>
+ * For IRunIterator, this uses IteratorWrapper to wrap the 
+ * iterator as an IRun.  Runner and IteratorWrapper coordinate
+ * to handle fast-fail (aborting further iteration when an IRun fails).
+ * The IRunIterator itself may specify fast-fail by returning true
+ * from {@link IRunIterator#abortOnFailure()}, or clients can 
+ * register IRunIterator by Object or type for fast-failure using
+ * {@link registerFastFailIterator(IRunIterator)} or 
+ * {@link registerFastFailIterator(Class)}.
+ * This also ensures that 
+ * {@link IRunIterator#iterationCompleted()} is

+/** 
+ * Install programmatically using http URL.
+ * (Very strange that java tool classpath does not accept http URL's.)
+ *
+ * Example:
+ * <p><code>java -classpath aj-testing.jar org.aspectj.testing.util.WebInstall
+ *    http://aspectj.org/download/distribution/aspectj10-tools.jar -text
+ *    install.properties</code>
+ *
+ * <p>You can omit the <code>-text install.properties</code> if there is
+ * a file called "install.properties" in the current directory.
+ *
+ * <p>The properties file must define the properties 
+ * <code>output.dir</code> and <code>context.javaPath</code>
+ * in properties- and platform specifie ways.  
+ * For property values, a backslash must be escaped with another backslash,
+ * and directory separators should be valid. E.g., on Windows:
+ * <pre>output.dir=c:\\output\\dir
+ * context.javaPath=c:\\apps\\jdk1.3.1</pre>
+ *
+ * For an installer to complete programmatically,
+ * the output directory must be empty of colliding files.
+ * This will fail with a stack trace if anything goes wrong, except for
+ * simple input errors.  
+ *
+ * <p>You may also use this as a driver for the known installers
+ * by specifying the following options (-baseurl must be first):<pre>
+ *         -baseurl           {baseurl}
+ *         -version           {version}
+ *         -context.javaPath  {path to JDK}    (properties form)
+ *         -output.dir        {path to outDir} (properties form, including trailing /)
+ *         -outdir            {path to outDir} (actual form) </pre>
+ * such that URL=
+ * <code>{baseurl}<packagePrefix>{version}<packageSuffix>.jar</code>
+ * and paths to context.javaPath and output.dir are specified in 
+ * properties-compliant format
+ *
+ * @see ant script test-product.xml for example of installing from files
+ *      which can be driven from the command-line.
