The wrapper can indeed be made 100% interchangeable since both use the
WebKit API. So, users can finally install one or the other.

Here is a code snippet (this time from mySTEP AppKit and not really
tested):

- (id) initWithHTML:(NSData *)data documentAttributes:(NSDictionary
**)dict;
{
        return [self initWithHTML:data options:nil documentAttributes:dict];
}

- (id) initWithHTML:(NSData *)data baseURL:(NSURL *)url
documentAttributes:(NSDictionary **)dict;
{
        return [self initWithHTML:data options:[NSDictionary
dictionaryWithObject:url forKey:NSBaseURLDocumentOption]
documentAttributes:dict];
}

// reuse (this is not at all thread safe!)
static BOOL didLoadWebKit;
static WebView *webView;
static BOOL done;

- (void) webView:(WebView *)sender didFinishLoadForFrame:(WebFrame*)
frame
{
        NSLog(@"did finish loading main frame");
        if(frame == [sender mainFrame])
                done=YES;
}

- (id) initWithHTML:(NSData *)data options:(NSDictionary *)options
documentAttributes:(NSDictionary **)dict;
{
        // check for HTML like header before trying
        if(!didLoadWebKit)
                [[NSBundle bundleWithPath:@"/System/Library/Frameworks/
WebKit.framework"] load], didLoadWebKit=YES;    // dynamically load
        if(!webView)
                {
                webView=[[NSClassFromString(@"WebView") alloc]
initWithFrame:NSMakeRect(0.0, 0.0, 100.0, 100.0)];
                if(!webView)
                        return nil;     // can't initialize
                }
        [[webView mainFrame] loadData:data MIMEType:@"text/html"
textEncodingName:@"utf-8" baseURL:[options
objectForKey:NSBaseURLDocumentOption]];
        [self setFrameLoadDelegate:self];
        done=NO;
        while(!done)
                { // loading is not yet done
                [NSApp nextEventMatchingMask:NSAnyEventMask untilDate:[NSDate
dateWithTimeIntervalSinceNow:0.2] inMode:NSDefaultRunLoopMode
dequeue:NO];    // process events
                }
        if(dict)
                *dict=[NSDictionary dictionaryWithKeysAndAttributes:
                        NSHTMLTextDocumentType, NSDocumentTypeDocumentAttribute,
                        [[[webView mainFrame] dataSource] textEncodingName],
NSCharacterEncodingDocumentAttribute,   // may be nil?
                        [[[webView mainFrame] dataSource] pageTitle],
NSTitleDocumentAttribute,       // title may be nil!!!
                        nil];
        return [self initWithAttributedString:[[[[webView mainFrame]
frameView] documentView] attributedString]];
}
