-Creating a Subsurface bundle
-============================
-
-(we now have a small shell script that should automate this process;
- look for make-package.sh)
-
-After you build Subsurface and install it on your Mac
-
-make install-macosx
-
-you need gtk-mac-bundler (this has been tested with version 0.7.3); run
-
-  $ gtk-mac-bundler subsurface.bundle
-
-This should install an almost self-contained Subsurface application under
-./staging/Subsurface.app
-
-Sadly because of the way gettext accesses the gtk20.mo file, this fails
-for localized use - so I ended up building MacPorts with
--prefix /Applications/Subsurface.app/Contents/Resources
-And then things work correctly IFF the app gets installed with that path.
-
-What a pain.
-
-Worse, gtk-mac-bundler fails to catch the .so files that are part of the
-gdk-pixbuf loader infrastructure. So we need to manually adjust the load
-paths in them:
-
-cd packaging/macosx/staging/Subsurface.app/Contents
-for i in Resources/lib/gdk-pixbuf-2.0/2.10.0/loaders/* ; do \
-	~/gtk-mac-bundler/bundler/run-install-name-tool-change.sh $i \
-	/Applications/Subsurface.app/Contents/Resources Resources change ; \
-done
-
-Finally, you need to change the IDs of the libraries:
-
-for i in Resources/lib/*.dylib; do install_name_tool -id "@executable_path/../$i" $i; done
-
-Next you should sign your binaries if you plan to use them 10.8 (or later).
-
-Then you can use git://github.com/dirkhh/yoursway-create-dmg.git to create
-a DMG (use the readlink-fix branch - unless this has been pulled into the
-main project by the time you read this).
-
-Here is roughly how I run this to create the official DMG
-
-~/yoursway-create-dmg/create-dmg --background ./Subsurface-Background.png \
-	--window-size 500 300 --icon-size 96 \
-	--volname "Subsurface-${VERSION}" --app-drop-link 380 205 \
-	--volicon ~/subsurface/packaging/macosx/Subsurface.icns \
-	--icon "Subsurface" 110 205 ./Subsurface-${VERSION}.dmg ./staging
-
-The --volicon doesn't appear to work for me even though it does create the
-correct file in the DMG. I'm leaving it in here to remind me to
-investigate this issue.
-
-Caveats
--------
-
-* You need (at least with MacPorts) to build pango like this:
-
-  $ sudo port install pango +builtin_modules +no_x11 +quartz
-
-Without the builtin modules the installed application fails to find the
-modules and doesn't render any text.
-
-Also note the comment above about the -prefix
-
-* It seems that gtk-mac-bundler expects the charset.alias file to be
-  in the ${prefix}/lib folder which it isn't with the current version of
-  MacPorts. The following fixes that:
-
-  $ sudo cp /usr/lib/charset.alias /opt/local/lib
-
-* libdivecomputer needs to be configured with
-  --with-prefix=/Applications/Subsurface.app/Contents/Resources
-  as well.
