Revision history for File-Unpack

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
