-Mac OS X Instructions
-=====================
-
-0. Note:  since there is no XFS implementation on Mac OS X, you are
-   severely limited in what you can do.  mkfs.xfs(8), xfs_db(8) and
-   xfs_repair(8) are the only functional tools on this platform, as
-   they do not interact with the XFS kernel code at all.  Still, it
-   can be useful to have access to these utilities from Mac OS X in
-   a dual boot configuration, for example.
-
-   However, keep on mind that mkfs.xfs on Mac OS X has disabled
-   device access, although you can create a filesystem in a file.
-   Also note that existing filesystem detection is disabled.
-
-1. Configure, build and install the package
-
-   The xfsprogs package uses autoconf/configure and expects a GNU build
-   environment (your platform must at least have both autoconf, make,
-   and glibtool). 
-
-   You will also need to have built and installed the UUID library which
-   is provided by the e2fsprogs source package. (Or use Homebrew, Macports
-   or any other 3rd party package manager.)
-
-   Building libuuid:
-
-	[download; unzip/untar e2fsprogs; cd e2fsprogs]
-	$ ./configure --prefix=/usr --mandir=/usr/share/man
-	$ make lib/ext2fs/ext2_types.h
-	$ cd lib/uuid
-	$ make
-	$ su root
-	# make install
-	[verify that you now have a /usr/lib/libuuid.a]
-
-   Building xfsprogs:
-
-	[firstly set these environment variables to these values]
-	TAR=/usr/bin/gnutar
-	LIBTOOL=/usr/bin/glibtool
-	INSTALL_GROUP=wheel
-	LOCAL_CONFIGURE_OPTIONS="\
-				 --enable-gettext=no\
-				 --enable-blkid=no\
-				 --enable-librt=no\
-				 "
-
-	$ make
-	$ su root
-	# make install
-	[and optionally, for the development libraries and headers]
-	# make install-dev
