// maybe we should encapsulate QUrl instead of inheriting from it.

/**
 * \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.
