README

======

This project was first conceived to manipulate Apple's software restore

packages (IPSWs) and hence much of it is geared specifically toward that

format. Useful tools to read and manipulate the internal data structures of

those files have been created to that end, and with minor changes, more

generality can be achieved in the general utility. An inexhaustive list of

such changes would be selectively enabling folder counts in HFS+, switching

between case sensitivity and non-sensitivity, and more fine-grained control

over the layout of created dmgs.

**THE CODE HEREIN SHOULD BE CONSIDERED HIGHLY EXPERIMENTAL**

Extensive testing have not been done, but comparatively simple tasks like

adding and removing files from a mostly contiguous filesystem are well

proven.

Please note that these tools and routines are currently only suitable to be

accessed by other programs that know what they're doing. I.e., doing

something you "shouldn't" be able to do, like removing non-existent files is

probably not a very good idea.

This work is released under the terms of the GNU General Public License,

version 3. The full text of the license can be found in the LICENSE file.

DEPENDENCIES

------------

The HFS portion will work on any platform that supports GNU C and POSIX

conventions. The dmg portion has dependencies on zlib (which is included) and

libcrypto from openssl (which is not). If libcrypto is not available, remove

the -DHAVE_CRYPT flags from the CFLAGS of the makefiles. All FileVault

related actions will fail, but everything else should still work. I imagine

most places have libcrypto, and probably statically compiled zlib was a dumb

idea too.

USING

-----

The targets of the current repository are three command-line utilities that

demonstrate the usage of the library functions (except cmd_grow, which really

ought to be moved to catalog.c). To make compilation simpler, a complete,

unmodified copy of the zlib distribution is included. The dmg portion of the

code has dependencies on the HFS+ portion of the code. The "hdutil" section

contains a version of the HFS+ utility that supports directly reading from

dmgs. It is separate from the HFS+ utility in order that the hfs directory

does not have dependencies on the dmg directory.

The makefile in the root folder will make all utilities.

### HFS+

	cd hfs

	make

### DMG

	cd dmg/zlib-1.2.3

	./configure

	make

	cd ..

	make

### hdutil

	cd hdiutil

	make
