+/**
+ * <p>This interface supports the creation of new files by the
+ * annotation processor.  Creating files via this interface means
+ * that they can be tracked by the annotation processing tool.
+ * Once the file streams are closed, the tool will automatically
+ * consider them for processing.</p>
+ * <p>Files are separated into three types: source files, class
+ * files and resource files.  Two locations are defined; one
+ * for source files and one for class files (resource files
+ * may use either).  Locations are specified using a relative
+ * path separated by {@code '/'} and not including the
+ * segments {@code '.'} and {@code '..'} so that they may only
+ * refer to subdirectories.  A valid relative name must match
+ * the "path-rootless" rule of RFC 3986, section 3.3.</p>
+ * <p>The file creation methods take a variable number of
+ * originating elements, which can be used by the tool to
+ * handle dependency management.  For example, if a
+ * file is generated due to the presence of a particular
+ * method, the element representing that method may be
+ * specified as an originating element.  Whether this
+ * information is used by the tool or not is left down
+ * to the implementator.</p>
+ * <p>Each run of the annotation processing tool may only
+ * create a file with a given pathname once.  Attempts
+ * to create the same file a second time will result in
+ * a {@link FilerException}.  The same behaviour results
+ * from trying to overwrite the initial source files, which
+ * are classed as being created in the zeroth round of
+ * processing.  The same exception will be thrown if
+ * the same name is used for both a source file and a
+ * class file.</p>
+ * <p>Processors must not knowingly attempt to overwrite
+ * files that weren't generated by themselves or a similar
+ * tool.  Similarly, the user invoking the tool should
+ * not configure it so that it will end up overwriting
+ * files that weren't generated.  A {@code Filer}
+ * implementation may include safeguards so as not to
+ * overwrite class files such as {@code java.lang.Object}.</p>
+ * <p>The {@link javax.lang.annotation.Generated}
+ * annotation is available to denote generated files
+ * if needed.  Some of the effect of overwriting files may
+ * be achieved by using a decorator-style design
+ * pattern and either a generated superclass or a series
+ * of generated subclasses.  In the latter case,
+ * the class would provide the appropriate generated
+ * subclass via the factory pattern.</p>
