/**
* \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.
*
