This is a description of the files in this directory, all of which have
to do with packaging on Mac OS X. They are useful only for those wanting
to build binary distributions of Zenmap for Mac OS X.

== Info.plist
A properties list file that whose contents are merged with the default
properties added by py2app.

== make-bundle.sh
This script builds a .app bundle. It must be run from the root of the
Zenmap source tree. The finished bundle is put in dist/Zenmap.app.

== test_wrapper.py
This file contains unit tests for zenmap_wrapper.py, because it needs to
do some tricky escaping and substitution of configuration files.

== zenmap.icns
The icon file for the bundle. It was created using the Icon Composer
utility as described at
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjCTutorial/08Configuring/08Configuring.html

== zenmap_auth.c
This is a simple wrapper program that attempts to run zenmap_wrapper.py
with privileges.

== zenmap_wrapper.py
This is a wrapper script that gets installed in the application bundle.
It sets up an execution environment and then calls the main zenmap
executable.

== MacPorts-ports.diff

This patch against a MacPorts ports tree contains various changes needed
to install dependencies in a sufficiently portable way. The main thing
accomplished by this patch is to avoid building a MacPorts libiconv.
libcups depends on libiconv, but it depends on an Apple version of
libconv, and MacPorts doesn't have a port for libcups. The MacPorts
libiconv is incompatible and causes a dynamic linker error at runtime.

The following instructions show how to make a 10.5-compatible
environment suitable for building Zenmap packages. It will be a separate
installation in $HOME/macports-10.5 that won't interfere with your
normal MacPorts installation in /opt/local. These instructions were done
with MacPorts 2.0.3 on Mac OS X 10.6.8.

1. Install MacPorts.
	export PATH=/usr/bin:/bin:/usr/sbin:/sbin
	export PREFIX=$HOME/macports-10.5
	tar xzvf MacPorts-2.0.3.tar.gz
	cd MacPorts-2.0.3
	./configure --with-no-root-privileges --prefix=$PREFIX --with-tclpackage=$PREFIX/Library/Tcl --with-applications-dir=$PREFIX/Applications
	make
	make install
2. Update the ports tree.
	$PREFIX/bin/port sync
3. Edit the file $PREFIX/etc/macports/macports.conf.
   Uncomment the line
	build_arch			i386
   Add this line at the bottom:
	macosx_deployment_target	10.5
4. Make a local patched ports tree.
	cd $PREFIX
	mkdir ports
	ln -s var/macports/sources/rsync.macports.org/release/tarballs/ports ports.orig
	for x in devel/atk devel/gettext devel/glib2 gnome/gtk2 graphics/fontconfig perl/p5-locale-gettext python/py26-gobject python/py27-libxml2 textproc/help2man textproc/libxml2 textproc/libxslt; do
		mkdir -v -p ports/$x;
		cp -R ports.orig/$x ports/$(dirname $x);
	done
	patch -p0 < MacPorts-ports.diff
5. Build a port index.
	cd ports
	$PREFIX/bin/portindex
6. Edit the file $PREFIX/etc/macports/sources.conf.
   Add a line
	file:///Users/user/macports-10.5/ports
   above the rsync line. (Replace "user" with your user name.)
7. Install the dependencies of Zenmap.
	$PREFIX/bin/port install py26-gtk py26-py2app

Here are instructions for updating the patch to keep up with MacPorts
changes. First, sync the original ports tree.
	$PREFIX/bin/port sync
Restore a pristine partial ports tree:
	cd $PREFIX
	rsync -rv --existing --delete --exclude=PortIndex ports.orig/ ports/
Reapply the patch. Resolve any conflicts.
	patch -p0 --no-backup-if-mismatch < MacPorts-ports.diff
Make a new patch.
	diff --unidirectional-new-file -ru -x 'PortIndex*' ports.orig ports | grep -v '^Only in ' > new.diff
Check that it's all right, then rename it.
	mv new.diff MacPorts-ports.diff
Rebuild the port index.
	cd ports
	$PREFIX/bin/portindex
