+/**
+ * @brief 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.
+ *
+ * For examle:
+ * - '#' -> "%23"
+ * (In a URL the hash-character @c '#' is used to specify a "reference", i.e.
+ * the position within a document)
+ * - space -> "%20"
+ *
+ * The constructor KURL(const TQString&) expects a string properly escaped,
+ * or at least non-ambiguous.
+ * For instance a local file or directory <tt>"/bar/#foo#"</tt> would have the
+ * URL <tt>"file:///bar/%23foo%23"</tt>.
+ * If you have the absolute path and need the URL-escaping you should create
+ * KURL via the default-constructor and then call setPath(const TQString&):
+ * @code
+ * KURL kurl;
+ * kurl.setPath( "/bar/#foo#" );
+ * TQString 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 path().
+ * @code
+ * KURL url( "file:///bar/%23foo%23" );
+ * ...
+ * if ( url.isLocalFile() )
+ * TQString path = url.path(); // -> "/bar/#foo#"
+ * @endcode
+ *
+ * The other way round: if the user can enter a string, that can be either a
+ * path or a URL, then you need to use KURL::fromPathOrURL() to build a KURL.
+ *
+ * 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
+ * TQString dirUrl = "file:///bar/";
+ * TQString fileName = "#foo#";
+ * TQString 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/" );
+ * TQString fileName = "#foo#";
+ * url.addPath( fileName );
+ * TQString 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");
+ * TQString visibleURL = url.prettyURL(); // -> "ftp://name@ftp.faraway.org/bar/%23foo%23"
+ * @endcode
+ * Note that prettyURL() doesn't change the character escapes (like <tt>"%23"</tt>).
+ * Otherwise the URL would be invalid and the user wouldn't be able to use it in another
+ * context.
+ *
+ * KURL has some restrictions regarding the path
+ * encoding. KURL works internally with the decoded path and
+ * and encoded query. For example,
+ * @code
+ * http://localhost/cgi-bin/test%20me.pl?cmd=Hello%20you
+ * @endcode
+ * would result in a decoded path <tt>"/cgi-bin/test me.pl"</tt>
+ * and in the encoded query <tt>"?cmd=Hello%20you"</tt>.
+ * Since path is internally always encoded you may @em not use
+ * <tt>"%00"</tt> in the path, although this is OK for the query.
