Instructions for installing a SafariBeta as a self-contained .app . Licensing terms (aka: covering my ***) are at the bottom.


1. Get WebKitLauncher as a binary, or build it (see below). You can just unzip WebKitLauncher.zip here.

2. Get the Safari Beta parts for WebKitLauncher to use:
   A. Download the beta, mount the disk image.
   B. Open a terminal, cd to wherever you like.
   C. Make sure WebKitLauncher.app is in your terminal's current dir,
      and copy the .pkg installer there too.
   
   D. Extract the .pkg into a 'BetaFiles' directory
        mkdir BetaFiles; cd BetaFiles
        xar -xf ../Safari4.0BetaLeo.pkg
        pax -rz -pp -f Safari4.0BetaLeo.pkg/Payload
        cd ..

   E. Extract the bits we need into WKL.app, these are all the frameworks and
      Safari.app. You can just run this at the terminal:
        cp -R BetaFiles/Applications/* WebKitLauncher.app/Contents/Resources/
        find BetaFiles -name \*.framework \
            | /usr/bin/xargs -J% cp -R % WebKitLauncher.app/Contents/Resources/
        find WebKitLauncher.app/Contents/Resources/ -name Frameworks \
            | /usr/bin/xargs rm -r
    
    F. Fix the version in the Info.plist (replace '4.0 beta' with the whatever
           version you like):
         perl -i -pe 's/r?VERSION/4.0 beta/g' \
           WebKitLauncher.app/Contents/Info.plist
         touch WebKitLauncher.app

3. Clean up:
   A. Unmount and trash the Safari beta disk image, and move WebKitLauncher.app
      wherever you like: "/Applications/Safari beta.app" works for me.
  
   B. Get rid of the BetaFiles directory and the .pkg you copied.
  
   C. Optionally, give Safari Beta a distinctive icon. See compass.psd for a
      sample.

4. (optional) Make sure your plugins won't interfere with the beta. My patch to
   WebKitLauncher allows it to use an auxiliary prefs file that regular Safari
   won't see.
   
   A. Make a plist (Property List Editor is the easiest way), and add to it
      one of the following two items:
      
      i. NSUseCocoaInputServers (Boolean)
          If set to 'NO', disables all plugins (InputManagers) while
          running Safari beta.
      
      ii. NSDisabledInputManagers (Array of strings)
          A list of plugins to disable while running Safari beta, for
          example 'Saft', 'Sogudi', etc.
   
   B. Save as ~/Library/Preferences/SafariBeta.plist



Appendix A - Building WebKitLauncher yourself
   A. If you're still on 10.4, install SVN
	  (from fink, MacPorts, http://homepage.mac.com/hiirem/svkbuilds.html, ...)
   
   B. Checkout WKL source
        svn co http://svn.webkit.org/repository/webkit/trunk/WebKitTools/WebKitLauncher
        cd WebKitLauncher
   
   C. Patch it for location of Safari.app. By default WebKitLauncher will use
      /Applications/Safari.app, but we want it to use the Safari.app inside
      its resources dir. Assuming my patches dir is nearby:
        patch -p1 < ../patches/app-location.patch
   
   D. Optionally, apply two more patches: One to build as a universal binary,
      the second my hack to allow an auxiliary preferences file for Safari beta: 
        patch -p1 < ../patches/universal.patch
        patch -p1 < ../patches/custom-prefs.patch
  
   E. Build it
        xcodebuild -target WebKit -configuration Release
   
   F. Now WebKit.app is in ./build/Release/WebKit.app, you can rename it to
      WebKitLauncher.app and get rid of everything else.


Appendix B - Creating a standalone Safari from your system

You might want to create a Safari based on what's on your system, for example
if you're about to upgrade to a new Safari. Just replace stages 2D and 2E with:

   DE.
      cp -R /Applications/Safari.app WebKitLauncher.app/Contents/Resources/
      /usr/bin/find -E /System/Library/{Frameworks,PrivateFrameworks} -regex \
        '.*/(JavaScript(Core|Glue)|PubSub|Symbolication|SyndicationUI|Web(Core|Kit)).framework' \
        | /usr/bin/xargs -J% cp -R % WebKitLauncher.app/Contents/Resources/
      find WebKitLauncher.app/Contents/Resources/ -name Frameworks \
        | /usr/bin/xargs rm -r

    

COPYING:
  * WebKitLauncher is part of the WebKit project, licensed under the LGPL.
  * Safari and its frameworks are mostly (C) Apple, but I'm not distributing them.
  * The icon compass.icns is taken from Safari and is thereforce (C) Apple, compass-4.0b.icns is derived from it. They're small, and I'm only using them to label Apple's own app, so I'm claiming fair use--but I'll remove them if asked.
  * All other files in this distribution are hereby placed in the public domain: HOWTO.txt,  SafariBeta.plist, and the patches.
