0.32	jw, Thu Mar 10 01:52:53 CET 2011
	Fixed setlimit code, to be more robust.
	Fixed logfile JSON syntax, with a dummy Element in the epilog.
	Added 06-logfile.t to test the logfile syntax.

0.31	jw, Wed Mar  9 00:01:50 CET 2011
	Added list() method.
	Spellchecked pod.

0.30 	jw, Fri Nov 19 19:13:53 CET 2010

        (walde.christian@googlemail.com)

0.29	jw, Tue Dec 14 23:19:02 CET 2010
	Mention /usr/bin/file_unpack in perldoc

0.28	jw, Fri Oct 22 14:29:09 CEST 2010
	Look only at files and dirs, ignore special files.
	Reading a pipe could block us endlessly.

0.27	jw, Sat Sep 11 22:01:49 CEST 2010
	new feature in mime(): attempt full file access
	not only if flm reports currupt, but also when it reports
	a/octet-stream. this helps to recognize a/x-iso9660-image
	Added .iso by including my old unpack_iso.pl as a helper.
	Added .lha

0.26	jw, Thu Sep  9 19:26:21 CEST 2010
	Added .upx; we are testing all application/*-executable for upx to get
	the mime type.  Fixed test results on SLE-11, 02-mime.t now can match
	regexp too.

0.25	jw, Wed Sep  8 21:44:37 CEST 2010
	Added .cpio, .deb, .cab, .7z
	Removed stupid debug die in helper.
	Removed done_testing() for the sake of old Test::More on 11.1

0.23	jw, Wed Sep  1 23:17:52 CEST 2010
	Added option one_shot, to new() and file_unpack.pl
	Added unpacking of: application/pdf, %tar+lzma, %rar, %uuencode
	Added '# Requires: ....' comments with the builtin handlers to document 
	the non-perlish dependencies. 
	Fixed recognition of .xls -- File::LibMagic said corrupt, with only a
	short buffer.  Swapped 2nd and 3rd parameter of _run_mime_handler():
	mime helpers have now their suggested destname as second parameter.
	mime(): added suffix rules for 'text/plain' and 'application/octet-stream', 
	to harvest even the least trusted source of information, in the absence
	of anything else.
	Implemented first draft of helper/text/=x-shellscript: tested embedded gzip.
	Added -L option to file_unpack.pl; 
	_run_mime_handler() now untaints its argv. run() errors are now propagated.
	t/04-subdir.t now does a real-life unzip test, if unzip is available.
	Lowered $RECURSION_LIMIT to 200. 1000 takes ages with big files.
	Call bunzip2 with -f, but don't call xz with -f.
	Fixed unpack() to not hit 256 char limit per filename so easily.
	Tested mime_handler_dir(), now it actually works. Introduced a default directory
	/usr/share/File-Unpack/helper.
	Preparing env variable PERL5LIB for helpers.
	mime(): Fixed usage of LZMA alone decoder: count as positive, only of output appeared.
	text/x-shellscript: uudecode and shar support tested; works now.

0.22	jw, Sun Aug 29 23:27:59 CEST 2010
	Fixed descending of destdir into subdirs of subdirs
	Added t/04-subdir.t, 
	Added first support for running unpack() under -T
	Replaced MANIFEST.SKIP with a filter in t/manifest.t
	Fixed t/02-mime.t to survive missing shared-mime-info.
	(Makefile.PL cannot require non-perl packages, can it?)

0.21	jw, Wed Aug 25 22:15:48 CEST 2010
        Added 'nothing-to-do' semantic for mime-helpers: Point back by symlink.
   	Added helper/text=x-shellscript to demonstrate this.
	Made external mime-helpers work: registering, calling.
	Remember absolut path, call mime_type() correctly.
	Started to propagate errors from _run_mime_handler() to unpack().
	mime(): In SLES11 we get 'text/plain charset=utf-8' without semicolon.

0.20	jw, Tue Aug 24 21:15:49 CEST 2010
	POD polishing. Synopsis now has some illustrative code.

0.19	jw, Tue Aug 24 15:42:49 CEST 2010
	Added _finalize_argvv() to call _locate_*() functions only if 
	find_mime_handler() needs it. Added _locate_tar() and _locate_cpio_i;
	Converted sub _builtin_mime_handlers back into @builtin_mime_handlers;
	Debugged run(); piping was broken. Made new(jail_chmod0 => 1) optional.

0.18	jw, Tue Aug 24 02:13:47 CEST 2010
	Added handlers for x-tar+bzip2, x-tar+gzip, x-rpm;
	Converted @builtin_mime_handlers into sub _builtin_mime_handlers;
	Converted system() tests of tar options to run() tests. Added tests for 
	cpio too. Secured pump inside eval {}. 
	Added fmt_run_shellcmd() to the API; thus fixed file_unpac.pl -m ...

0.17	jw, Mon Aug 23 11:36:04 CEST 2010
	Made the test suite run again with -t

0.16	jw, Mon Aug 23 01:28:09 CEST 2010
	added tar handler. debugged dir unpacking, copy-in, 
	destdir=jail, and def_mime_handler_fmt.

0.15	jw, Mon Aug 16 01:08:32 CEST 2010
	destroyed unpack(): recreated subdir code. To be completed.

0.14	jw, Thu Aug 12 00:14:00 CEST 2010
	Using Text::Sprintf::Named for parsing builtin_mime_handlers.
	Added _fmt_run_shellcmd(). Tested _run_mime_handler. Finished.

0.13	jw, Wed Aug 11 10:30:49 CEST 2010
	regression fixed: application/oasis.*.text no longer had +zip suffix.

0.12	jw, Fri Aug  6 01:38:50 CEST 2010
	Possibly finalized _run_mime_handler(), needs testing.

0.11    jw, Tue Aug  3 20:15:04 CEST 2010
	Reporting @missing_unpacker in log.

0.10	jw, Tue Aug  3 00:30:25 CEST 2010
	File::Unppack::run() finished. Oops, IPC::Run opens all redirects before init. 
	Jail construction done in _run_mime_handler(). Jail descruction TBD.
	@builtin_mime_handlers now reflects the harness structure, knows which
	suffixes to remove, and uses words in curly braces as templates, to
	make it less ugly.  Delayed template substitution into
	_run_mime_handler(), as extra array-refs are no good idea in a harness.

0.09    jw, Sun Aug  1 23:42:19 CEST 2010
	Added self->{done}, to protect against re-unpacking; enabled recursion in unpack.
	More consistent use of C<...> in POD. _run_mime_handler() prepared for IPC::Run.
	Changed use_mime_handler() to parse an array, rather than a format string.

0.08	jw, Mon Jul 12 00:54:09 CEST 2010
	Added mime handler methods: use_mime_handler_dir(), use_mime_handler(),
	find_mime_handler() using $self->{mime_orcish};
	Added builtin handlers to new(), using "%{destdir} ..." format string syntax
	Added _prep_configdir(), shell and json support.
	Continued unpack() to dispatch into mime handlers.
	Started _run_mime_handler()

0.07    jw, Fri Jul  9 01:19:19 CEST 2010
	Added support for stacked compressions recognition without looking 
	at file suffixes at all:
	mime(file => '.tar.gz.lzma') says: "application/x-tar+gzip+lzma"
	Hack to make tar.bz2 appear as "application/x-tar+bzip2"
	tar.bz2.lzma does not work, that is why I call bz2 support a hack.
	Now we can work on efficient unpack helpers.

0.06	jw, Thu Jul  8 00:31:24 CEST 2010
	using Compress::Raw::Lzma::AloneDecoder instead  of lzcat.

0.05	jw, Wed Jun 30 01:35:17 CEST 2010
	started unpack(), added _not_excluded(),
	added file_unpack.pl for testing.

0.04	jw, Mon Jun 28 21:38:31 CEST 2010
	added exclude(), with tests & docs.
	added _fs_check() and _fs_warn() logic.
	added and used _bytes_unit().

0.03	jw, Sun Jun 27 03:09:21 CEST 2010
	new() completed, private log(), logf() added.

0.02	jw, Sat Jun 26 21:55:12 CEST 2010
	mime() documented, implemented, tested.

0.01    jw, Sat Jun 26 12:45:63 CEST 2010
        First version, skeleton drafted.
