	/**
	* \class KUrl kurl.h <KUrl>
	*
	* Represents and parses a URL.
	*
	* A prototypical URL looks like:
	* \code
	* protocol://user:password\@hostname:port/path/to/file.ext#reference
	* \endcode
	*
	* KUrl handles escaping of URLs. This means that the specification
	* of a full URL will differ from the corresponding string that would specify a
	* local file or directory in file-operations like fopen. This is because an URL
	* doesn't allow certain characters and escapes them. (e.g. '#'->"%23", space->"%20")
	* (In a URL the hash-character '#' is used to specify a "reference", i.e. the position
	* within a document).
	*
	* The constructor KUrl(const QString&) expects a string properly escaped,
	* or at least non-ambiguous.
	* If you have the absolute path you should use KUrl::fromPath(const QString&).
	* \code
	* KUrl kurl = KUrl::fromPath("/bar/#foo#");
	* QString url = kurl.url(); // -> "file:///bar/%23foo%23"
	* \endcode
	*
	* If you have the URL of a local file or directory and need the absolute path,
	* you would use toLocalFile().
	* \code
	* KUrl url( "file:///bar/%23foo%23" );
	* ...
	* if ( url.isLocalFile() )
	* QString path = url.toLocalFile(); // -> "/bar/#foo#"
	* \endcode
	*
	* This must also be considered when you have separated directory and file
	* strings and need to put them together.
	* While you can simply concatenate normal path strings, you must take care if
	* the directory-part is already an escaped URL.
	* (This might be needed if the user specifies a relative path, and your
	* program supplies the rest from elsewhere.)
	*
	* Wrong:
	* \code
	* QString dirUrl = "file:///bar/";
	* QString fileName = "#foo#";
	* QString invalidURL = dirUrl + fileName; // -> "file:///bar/#foo#" won't behave like you would expect.
	* \endcode
	* Instead you should use addPath():
	* Right:
	* \code
	* KUrl url( "file:///bar/" );
	* QString fileName = "#foo#";
	* url.addPath( fileName );
	* QString validURL = url.url(); // -> "file:///bar/%23foo%23"
	* \endcode
	*
	* Also consider that some URLs contain the password, but this shouldn't be
	* visible. Your program should use prettyUrl() every time it displays a
	* URL, whether in the GUI or in debug output or...
	*
	* \code
	* KUrl url( "ftp://name:password@ftp.faraway.org/bar/%23foo%23");
	* QString visibleURL = url.prettyUrl(); // -> "ftp://name@ftp.faraway.org/bar/%23foo%23"
	* \endcode
	* Note that prettyUrl() doesn't change the character escapes (like "%23").
	* Otherwise the URL would be invalid and the user wouldn't be able to use it in another
	* context.
	*
