-Usage
+Standard Usage
-=====
+==============
+    Standard usage consists of a few common options to control basic behavior. A variety of
+    parameters including global deduplication are automatically set based on the compression
+    level.
 
-    To compress a file:
+    Archiving
-       pcompress -c <algorithm> [-l <compress level>] [-s <chunk size>] <file> [-]
+    ---------
+       pcompress -a [-v] [-l <compress level>] [-s <chunk size>] [-c <algorithm>]
+                    [<file1> <directory1> <file2> ...] [-t <number>] [-S <chunk checksum>]
+                    <archive filename or '-'>
 
-       Where <algorithm> can be the folowing:
+       Archives a given set of files and/or directories into a compressed PAX archive. The
-       lzfx   - Very fast and small algorithm based on LZF.
+       PAX datastream is encoded into a custom format compressed file that can only be
-       lz4    - Ultra fast, high-throughput algorithm reaching RAM B/W at level1.
+       handled by Pcompress.
-       zlib   - The base Zlib format compression (not Gzip).
-       lzma   - The LZMA (Lempel-Ziv Markov) algorithm from 7Zip.
-       lzmaMt - Multithreaded version of LZMA. This is a faster version but
-                uses more memory for the dictionary. Thread count is balanced
-                between chunk processing threads and algorithm threads.
-       bzip2  - Bzip2 Algorithm from libbzip2.
-       ppmd   - The PPMd algorithm excellent for textual data. PPMd requires
-                at least 64MB X CPUs more memory than the other modes.
 
-       libbsc - A Block Sorting Compressor using the Burrows Wheeler Transform
+       -a       Enables archive mode where pathnames specified in the command line are
-                like Bzip2 but runs faster and gives better compression than
+                archived using LibArchive and then compressed.
-                Bzip2 (See: libbsc.com).
 
-       adapt  - Adaptive mode where ppmd or bzip2 will be used per chunk,
+       -l <compress level>
-                depending on heuristics. If at least 50% of the input data is
+                Select a compression level from 1 (least compression, fastest) to 14
-                7-bit text then PPMd will be used otherwise Bzip2.
+                (ultra compression, slow). Default: 6
-       adapt2 - Adaptive mode which includes ppmd and lzma. If at least 80% of
-                the input data is 7-bit text then PPMd will be used otherwise
-                LZMA. It has significantly more memory usage than adapt.
-       none   - No compression. This is only meaningful with -D and -E so Dedupe
-                can be done for post-processing with an external utility.
 
-       <chunk_size> - This can be in bytes or can use the following suffixes:
+       -s <chunk size>
-                g - Gigabyte, m - Megabyte, k - Kilobyte.
+                Archive data is split into chunks that are processed in parallel. This value
-                Larger chunks produce better compression at the cost of memory.
+                specifies the maximum chunk size. Blocks may be smaller than this. Values
-                In case of Global Deduplication (see below) this chunk size is
+                can be in bytes or <number><suffix> format where suffix can be k - KB, m - MB,
-                just a hint and may get automatically adjusted.
+                g - GB. Default: 8m
-       <compress_level> - Can be a number from 0 meaning minimum and 14 meaning
+                Larger chunks can produce better compression at the cost of memory.
-                maximum compression.
-       '-'    - If '-' is given as the final argument then it specifies that
-                compressed output should go to stdout.
 
-NOTE: The option "libbsc" uses  Ilya Grebnov's block sorting compression library
+       -c <algorithm>
-      from http://libbsc.com/ . It is only available if pcompress in built with
+                Specifies the compression algorithm to use. Default algorithm when archiving
-      that library. See INSTALL file for details.
+                is adapt2 (Second Adaptive Mode). This is the ideal mode for archiving giving
+                best compression gains. However adapt (Adaptive Mode) can be used which is a
+                little faster but give lower compression gains.
+                Other algorithms can be used if all the files are of the same known type. For
+                example ppmd (slow) or libbsc (fast) can be used if all the files only have
+                ASCII text. See section "Compression Algorithms" for details.
 
-    To decompress a file compressed using above command:
+       -v       Enables verbose mode where each file/directory is printed as it is processed.
-       pcompress -d <compressed file> <target file>
 
-    <compressed file> can be '-' to indicate reading from stdin while write goes
+       -t <number>
-    to <target file>
+                Sets the number of threads that Pcompress can use. Pcompress automatically
+                uses thread count = core count. However with larger chunk size (-s option)
+                and/or ultra compression levels, large amounts of memory can be used. In this
+                case thread count can be reduced to reduce memory consumption.
 
-    To operate as a full pipe, read from stdin and write to stdout:
+       -S <chunk checksum>
-       pcompress -p ...
+                Specify then chunk checksum to use. Default: BLAKE256. The following checksums
-
+                are available:
-    Attempt Rabin fingerprinting based deduplication on chunks:
-       pcompress -D ...
-       pcompress -D -r ... - Do NOT split chunks at a rabin boundary. Default
-                             is to split.
-
-    Perform Delta Encoding in addition to Identical Dedup:
-       pcompress -E ... - This also implies '-D'. This performs Delta Compression
-                          between 2 blocks if they are 40% to 60% similar. The
-                          similarity %age is selected based on the dedupe block
-                          size to balance performance and effectiveness.
-       pcompress -EE .. - This causes Delta Compression to happen if 2 blocks are
-                          at least 40% similar regardless of block size. This can
-                          effect greater final compression ratio at the cost of
-                          higher processing overhead.
-
-    Number of threads can optionally be specified: -t <1 - 256 count>
-    Other flags:
-       '-L' -     Enable LZP pre-compression. This improves compression ratio of all
-                  algorithms with some extra CPU and very low RAM overhead. Using
-                  delta encoding in conjunction with this may not always be beneficial.
-                  However Adaptive Delta Encoding is beneficial along with this.
-
-       '-P' -     Enable Adaptive Delta Encoding. It can improve compresion ratio further
-                  for data containing tables of numerical values especially if those are
-                  in an arithmetic series. In this implementation basic Delta Encoding is
-                  combined with Run-Length encoding and Matrix transpose
-       NOTE -     Both -L and -P can be used together to give maximum benefit on most
-                  datasets.
-

-            - Specify chunk checksum to use:

+
+       -m        Enable restoring *all* permissions, ACLs, Extended Attributes etc.
+                 Equivalent to the '-p' option in tar. Ownership is only extracted if run as
+                 root user.
+       -K        Do not overwrite newer files.
+       -i        Only list contents of the archive, do not extract.
+
+       -m and -K are only meaningful if the compressed file is an archive. For single file
+       compressed mode these options are ignored.
+
+       <compressed file>
+                Specifies the compressed file or archive. This can be '-' to indicate reading
+                from stdin while write goes to <target file>
+
+       <target file or directory>
+                This can be a filename or a directory depending on how the archive was created.
+                If single file compression was used then this can be the name of the target
+                file that will hold the uncompressed data.
+                If this is omitted then an output file is created by appending '.out' to the
+                compressed filename.
+
+                If Archiving was done then this should be the name of a directory into which
+                extracted files are restored. The directory is created if it does not exist.
+                If this is omitted the files are extracted into the current directory.

+Compression Algorithms
+======================
+
+    lzfx    - Fast, average compression. At high compression levels this can be faster
+              than LZ4.
+              Effective Levels: 1 - 5
+    lz4     - Very Fast, sometimes better compression than LZFX.
+              Effective Levels: 1 - 3
+    zlib    - Fast, better compression.
+              Effective Levels: 1 - 9
+    bzip2   - Slow, much better compression than Zlib.
+              Effective Levels: 1 - 9
+
+    lzma    - Very slow. Extreme compression. Recommended: Use lzmaMt variant mentioned
+              below.
+              Effective Levels: 1 - 14
+              Till level 9 it is standard LZMA parameters. Levels 10 - 12 use
+              more memory and higher match iterations so are slower. Levels
+              13 and 14 use larger dictionaries upto 256MB and really suck up
+              RAM. Use these levels only if you have at the minimum 4GB RAM on
+              your system.
+    lzmaMt  - This is the multithreaded variant of lzma and typically runs faster.
+              However in a few cases this can produce slightly lesser compression
+              gain.
+
+    libbsc  - This is a new block-sorting compressor having much better effectiveness
+              and performance over a variety of data types as compared to Bzip2.
+    NOTE:     In the LGPL licensed version libbsc is an integral part of Pcompress.
+              When building MPLv2 licensed sources, the libbsc sources must be
+              downloaded separately and linked in. This is described in the INSTALL file.
+
+    PPMD    - Slow. Extreme compression for Text, average compression for binary.
+              In addition PPMD decompression time is also high for large chunks.
+              This requires lots of RAM similar to LZMA. PPMd requires
+              at least 64MB X core-count more memory than the other modes.
+              Effective Levels: 1 - 14.
+
+    Adapt   - Synthetic mode with text/binary detection. For pure text data PPMD is
+              used otherwise Bzip2 is selected per chunk.
+              Effective Levels: 1 - 14
+    Adapt2  - Slower synthetic mode. For pure text data PPMD is otherwise LZMA is
+              applied. Can give very good compression ratio when splitting file
+              into multiple chunks.
+              Effective Levels: 1 - 14
+              Since both LZMA and PPMD are used together memory requirements are
+              large especially if you are also using extreme levels above 10. For
+              example with 100MB chunks, Level 14, 2 threads and with or without
+              dedupe, it uses upto 2.5GB physical RAM (RSS).
+
+    none    - No compression. This is only meaningful with -G or -D. So Dedupe
+              can be done for post-processing with an external utility.
+
+Enabled features based on Compression Level
+===========================================
+
+    1 to 3  - No features, just compression and archiving, if needed.
+    4       - Global Deduplication with avg block size of 8KB.
+    5       - Global Dedup block size 8KB, Adaptive Delta Encoding.
+    6 to 8  - Global Dedup block size reduced to 4KB, Adaptive Delta Encoding.
+    9       - Global Dedup block size reduced to 2KB, Adaptive Delta Encoding, Dispack.
+    10      - Global Dedup block size 2KB, Adaptive Delta Encoding with extra rounds, Dispack,
+              LZP Preprocessing
+    10 - 14 - Global Dedup block size 2KB, Adaptive Delta Encoding with extra rounds, Dispack,
+              LZP Preprocessing, PackJPG filter for Jpegs.
+
+    NOTE:   - LZP Preprocessing and PackJPG are not available in the MPLv2 licensed version.
+
+Encryption
+==========
+    Pcompress supports encryption and authentication in both archive and single-file
+    compresion modes. Encryption options are discussed below.
+
+    NOTE: When using pipe-mode via -p the only way to provide a password is to use '-w'.
+          See below.
+
+       -e <ALGO>
+                Encrypt chunks using the given encryption algorithm. The algo parameter
+                can be one of AES or SALSA20. Both are used in CTR stream encryption
+                mode.
+                The password can be prompted from the user or read from a file. Unique
+                keys are generated every time pcompress is run even when giving the same
+                password. Of course enough info is stored in the compresse file so that
+                the key used for the file can be re-created given the correct password.
+
+                Default key length if 256 bits but can be reduced to 128 bits using the
+                '-k' option.
+
+                The Scrypt algorithm from Tarsnap is used
+                (See: http://www.tarsnap.com/scrypt.html) for generating keys from
+                passwords. The CTR mode AES mechanism from Tarsnap is also utilized.
+
+       -w <pathname>
+                Provide a file which contains the encryption password. This file must
+                be readable and writable since it is zeroed out after the password is
+                read.
+
+       -k <key length>
+                Specify the key length. Can be 16 for 128 bit keys or 32 for 256 bit
+                keys. Default value is 32 for 256 bit keys.
+
+
+Advanced usage
+==============
+    A variety of advanced options are provided if one wishes fine grained control
+    as opposed to automatic settings. If advanced options are used then auto-setting
+    of parameters get disabled. The various advanced options are discussed below.
+
+    Chunk-level Deduplication
+    -------------------------
+    Attempt Polynomial fingerprinting based deduplication on a per-chunk basis:
+       pcompress -D ...
+
+    Perform Delta Encoding in addition to Identical Dedup:
+       pcompress -E ... - This also implies '-D'. This performs Delta Compression
+                          between 2 blocks if they are 40% to 60% similar. The
+                          similarity %age is selected based on the dedupe block
+                          size to balance performance and effectiveness.
+       pcompress -EE .. - This causes Delta Compression to happen if 2 blocks are
+                          at least 40% similar regardless of block size. This can
+                          effect greater final compression ratio at the cost of
+                          higher processing overhead.
+
+       -F       Perform Fixed Block Deduplication. This is faster than fingerprinting
                 based content-aware deduplication in some cases. However this is mostly
                 usable for disk dumps especially virtual machine images. This generally
                 gives lower dedupe ratio than content-aware dedupe (-D) and does not
                 support delta compression.

archive/libarchive/INSTALL

@@ -0,0 +1,35 @@
+More complete build documentation is available on the libarchive
+Wiki:  http://libarchive.googlecode.com/
+
+On most Unix-like systems, you should be able to install libarchive,
+bsdtar, and bsdcpio using the following common steps:
+    ./configure
+    make
+    make install
+
+If you need to customize the target directories or otherwise adjust
+the build setting, use
+    ./configure --help
+to list the configure options.
+
+If you are developing libarchive and need to update the
+configure script and other build files:
+    /bin/sh build/autogen.sh
+
+To create a distribution, please use the 'distcheck' target:
+    /bin/sh build/autogen.sh && ./configure && make distcheck
+
+On Unix-like and non-Unix-like systems, use the "cmake" utility (available from
+http://cmake.org/) to generate suitable build files for your platform.
+Cmake requires the name of the directory containing CmakeLists.txt and
+the "generator" to use for your build environment.  For example, to
+build with Xcode on Mac OS, you can use the following command:
+    cmake -G "Xcode" ~/libarchive-download-dir/
+The result will be appropriate makefiles, solution files, or project
+files that can be used with the corresponding development tool.
+The default on Unix-like systems is to generate Makefiles, so you
+can also use cmake instead of the configure script:
+    cmake ~/libarchive-download-dir/
+    make
+    make install
+See the libarchive Wiki or the cmake site for further documentation.

+Jan 07, 2009: New archive_read_disk_entry_from_file() knows about ACLs,

+Jan 03, 2009: Read filter system extensively refactored.  In particular,
+	read filter pipelines are now built out automatically and individual

+Nov 08, 2008: Start of pre-release testing for libarchive 2.6
+
+Nov 07, 2008: Read filter refactor: The decompression routines just
+	consume and produce arbitrarily-sized blocks.  The reblocking
+	from read_support_compression_none() has been pulled into the
+	read core.  Also, the decompression bid now makes multiple
+	passes and stacks read filters.
+Oct 21, 2008: bsdcpio: New command-line parser.
+Oct 19, 2008: Internal read_ahead change: short reads are now an error
+Oct 06, 2008: bsdtar: option parser no longer uses getopt_long(),
+	gives consistent option parsing on all platforms.
+Sep 19, 2008: Jaakko Heinonen: shar utility built on libarchive
+Sep 17, 2008: Pedro Giffuni: birthtime support
+Sep 17, 2008: Miklos Vajna: lzma reader and test.  Note:  I still have
+	some concerns about the auto-detection (LZMA file format
+	doesn't support auto-detection well), so this is not yet
+	enabled under archive_read_support_compression_all().  For
+	now, you must call archive_read_support_compression_lzma() if
+	you want LZMA read support.
+Sep 11, 2008: Ivailo Petrov: Many fixes to Windows build, new solution files
+Jul 26, 2008: archive_entry now tracks which values have not been set.
+	This helps zip extraction (file size is often "unknown") and
+	time restores (tar usually doesn't know atime).
+Jul 26, 2008: Joerg Sonnenberger: Performance improvements to shar writer
+Jul 25, 2008: Joerg Sonnenberger: mtree write support
+
+Jul 02, 2008: libarchive 2.5.5 released

+Jun 20, 2008: bsdcpio: If a -l link fails with EXDEV, copy the file instead
+Jun 19, 2008: bsdcpio: additional long options for better GNU cpio compat
+Jun 15, 2008: Many small portability and bugfixes since 2.5.4b.
+
+May 25, 2008: libarchive 2.5.4b released
+May 21, 2008: Joerg Sonnenberger: fix bsdtar hardlink handling for newc format
+
+May 21, 2008: More progress on Windows building.  Thanks to "Scott"
+        for the Windows makefiles, thanks to Kees Zeelenberg for
+        code contributions.
+
+May 21, 2008: Fix a number of non-exploitable integer and buffer overflows,
+        thanks to David Remahl at Apple for pointing these out.
+
+May 21, 2008: Colin Percival: SIGINFO or SIGUSR1 to bsdtar prints progress info
+
+May 16, 2008: bsdtar's test harness no longer depends on file ordering.
+        This was causing spurious test failures on a lot of systems.
+        Thanks to Bernhard R. Link for the diagnosis.
+
+May 14, 2008: Joerg Sonnenberger: -s substitution support for bsdtar
+
+May 13, 2008: Joerg Sonnenberger: Many mtree improvements
+
+May 11, 2008: Joerg Sonnenberger: fix hardlink extraction when
+	hardlinks have different permissions from original file
+
+April 30, 2008: Primary libarchive work has been moved into the FreeBSD
+	project's Perforce repository: 	http://perforce.freebsd.org/
+	The libarchive project can be browsed at
+        //depot/user/kientzle/libarchive-portable
+        Direct link: http://preview.tinyurl.com/46mdgr
+
+May 04, 2008: libarchive 2.5.3b released
+	* libarchive: Several fixes to link resolver to address bsdcpio crashes
+	* bsdcpio: -p hardlink handling fixes
+	* tar/pax: Ensure ustar dirnames end in '/'; be more careful about
+	  measuring filenames when deciding what pathname fields to use
+	* libarchive: Mark which entry strings are set; be accurate about
+	  distinguishing empty strings ("") from unset ones (NULL)
+	* tar: Don't crash reading entries with empty filenames
+	* libarchive_test, bsdtar_test, bsdcpio_test:  Better detaults:
+	  run all tests, delete temp dirs, summarize repeated failures
+	* -no-undefined to libtool for Cygwin
+	* libarchive_test: Skip large file tests on systems with 32-bit off_t
+	* iso9660: Don't bother trying to find the body of an empty file;
+	  this works around strange behavior from some ISO9660 writers
+	* tar: allow -r -T to be used together
+	* tar: allow --format with -r or -u
+	* libarchive: Don't build archive.h
+
+May 04, 2008: Simplified building: archive.h is no longer constructed
+	This may require additional #if conditionals on some platforms.
+
+Mar 30, 2008: libarchive 2.5.1b released
+
+Mar 15, 2008: libarchive 2.5.0b released
+Mar 15, 2008: bsdcpio now seems to correctly write hardlinks into newc,
+	ustar, and old cpio archives.  Just a little more testing before
+	bsdcpio 1.0 becomes a reality.
+Mar 15, 2008: I think the new linkify() interface is finally handling
+	all known hardlink strategies.
+Mar 15, 2008: Mtree read fixes from Joerg Sonnenberger.
+Mar 15, 2008: Many new bsdtar and bsdcpio options from Joerg Sonnenberger.
+Mar 15, 2008: test harnesses no longer require uudecode; they
+	now have built-in decoding logic that decodes the reference
+	files as they are needed.
+
+Mar 14, 2008: libarchive 2.4.14 released; identical to 2.4.13 except for
+	a point fix for gname/uname mixup in pax format that was introduced
+	with the UTF-8 fixes.
+
+Feb 26, 2008: libarchive 2.4.13 released
+Feb 25, 2008: Handle path, linkname, gname, or uname that can't be converted
+	to/from UTF-8.  Implement "hdrcharset" attribute from SUS-2008.
+Feb 25, 2008: Fix name clash on NetBSD.
+Feb 18, 2008: Fix writing empty 'ar' archives, per Kai Wang
+Feb 18, 2008: [bsdtar] Permit appending on block devices.
+Feb 09, 2008: New "linkify" resolver to help with newc hardlink writing;
+	bsdcpio still needs to be converted to use this.
+Feb 02, 2008: Windows compatibility fixes from Ivailo Petrov, Kees Zeelenberg
+Jan 30, 2008: Ignore hardlink size for non-POSIX tar archives.
+
+Jan 22, 2008: libarchive 2.4.12 released
+Jan 22, 2008: Fix bad padding when writing symlinks to newc cpio archives.
+Jan 22, 2008: Verify bsdcpio_test by getting it to work against GNU cpio 2.9.
+	bsdcpio_test complains about missing options (-y and -z), format
+	of informational messages (--version, --help), and a minor formatting
+	issue in odc format output.  After this update, bsdcpio_test uncovered
+	several more cosmetic issues in bsdcpio, all now fixed.
+Jan 22, 2008: Experimental support for self-extracting Zip archives.
+Jan 22, 2008: Extend hardlink restore strategy to work correctly with
+	hardlinks extracted from newc cpio files.  (Which store the body
+	only with the last occurrence of a link.)
+

+
+Dec 29, 2007: libarchive 2.4.10 released
+Dec 29, 2007: bsdcpio 0.9.0 is ready for wider use.

+Dec 22, 2007: libarchive 2.4.9 released
+Dec 22, 2007: Implement the remaining options for bsdcpio:  -a, -q, -L, -f,
+	pattern selection for -i and -it.
+
+Dec 13, 2007: libarchive 2.4.8 released
+Dec 13, 2007: gzip and bzip2 compression now handle zero-byte writes correctly,
+	Thanks to Damien Golding for bringing this to my attention.

+
+Dec 10, 2007: libarchive 2.4.6 released

+
+Oct 30, 2007: libarchive 2.4.0 released
+Oct 30, 2007: Minor compile fix thanks to Joerg Schilling.
+Oct 30, 2007: Only run the format auction once at the beginning of the
+	archive.  This is simpler and supports better error recovery.
+Oct 29, 2007: Test support for very large entries in tar archives:
+	libarchive_test now exercises entries from 2GB up to 1TB.
+
+Oct 27, 2007: libarchive 2.3.5 released
+Oct 27, 2007: Correct some unnecessary internal data copying in the
+	"compression none" reader and writer; this reduces user time
+	by up to 2/3 in some tests.  (Thanks to Jan Psota for
+	publishing his performance test results to GNU tar's bug-tar
+	mailing list; those results pointed me towards this problem.)
+Oct 27, 2007: Fix for skipping archive entries that are exactly
+	a multiple of 4G on 32-bit platforms.
+Oct 25, 2007: Fix for reading very large (>8G) tar archives; this was
+	broken when I put in support for new GNU tar sparse formats.
+Oct 20, 2007: Initial work on new pattern-matching code for cpio; I
+	hope this eventually replaces the code currently in bsdtar.
+
+Oct 08, 2007: libarchive 2.3.4 released
+Oct 05, 2007: Continuing work on bsdcpio test suite.
+Oct 05, 2007: New cpio.5 manpage, updates to "History" of bsdcpio.1 and
+	bsdtar.1 manpages.
+Oct 05, 2007: Fix zip reader to immediately return EOF if you try
+	to read body of non-regular file.  In particular, this fixes
+	bsdtar extraction of zip archives.
+
+Sep 30, 2007: libarchive 2.3.3 released
+Sep 26, 2007: Rework Makefile.am so that the enable/disable options
+	actually do the right things.
+Sep 26, 2007: cpio-odc and cpio-newc archives no longer write bodies
+	for non-regular files.
+Sep 26, 2007: Test harness for bsdcpio is in place, needs more tests written.
+	This is much nicer than the ragtag collection of test scripts
+	that bsdtar has.
+
+Sep 20, 2007: libarchive 2.3.2 released
+Sep 20, 2007: libarchive 2.3.1 broke bsdtar because the archive_write_data()
+	fix was implemented incorrectly.
+
+Sep 16, 2007: libarchive 2.3.1 released
+Sep 16, 2007: Many fixes to bsdcpio 0.3:  handle hardlinks with -p, recognize
+	block size on writing, fix a couple of segfaults.
+Sep 16, 2007: Fixed return value from archive_write_data() when used
+	with archive_write_disk() to match the documentation and other
+	instances of this same function.
+Sep 15, 2007: Add archive_entry_link_resolver, archive_entry_strmode
+
+Sep 11, 2007: libarchive 2.2.8 released
+Sep 09, 2007: bsdcpio 0.2 supports most (not yet all) of the old POSIX spec.
+
+Sep 01, 2007: libarchive 2.2.7 released
+Aug 31, 2007: Support for reading mtree files, including an mtree.5 manpage
+	(A little experimental still.)
+Aug 18, 2007: Read gtar 1.17 --posix --sparse entries.
+Aug 13, 2007: Refined suid/sgid restore handling; it is no longer
+	an error if suid/sgid bits are dropped when you request
+	perm restore but don't request owner restore.
+Aug 06, 2007: Use --enable-bsdcpio if you want to try bsdcpio
+
+Aug 05, 2007: libarchive 2.2.6 released
+Aug 05, 2007: New configure option --disable-bsdtar, thanks to Joerg
+	Sonnenberger.
+Aug 05, 2007: Several bug fixes from FreeBSD CVS repo.
+
+Jul 13, 2007: libarchive 2.2.5 released
+
+Jul 12, 2007: libarchive 2.2.4 released
+Jul 12, 2007: Thanks to Colin Percival's help in diagnosing and
+	fixing several critical security bugs.  Details available at
+	http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc
+
+May 26, 2007: libarchive 2.2.3 released
+May 26, 2007: Fix memory leaks in ZIP reader and shar writer, add some
+	missing system headers to archive_entry.h, dead code cleanup
+	from Colin Percival, more tests for gzip/bzip2, fix an
+	EOF anomaly in bzip2 decompression.
+
+May 12, 2007: libarchive 2.2.2 released
+May 12, 2007: Fix archive_write_disk permission restore by cloning
+	entry passed into write_header so that permission info is
+	still available at finish_entry time.  (archive_read_extract()
+	worked okay because it held onto the passed-in entry, but
+	direct consumers of archive_write_disk would break).  This
+	required fixing archive_entry_clone(), which now works and has
+	a reasonably complete test case.
+May 10, 2007: Skeletal cpio implementation.
+
+May 06, 2007: libarchive 2.2.1 released
+May 06, 2007: Flesh out a lot more of test_entry.c so as to catch
+	problems such as the device node breakage before releasing <sigh>.
+May 05, 2007: Fix a bad bug introduced in 2.1.9 that broke device
+	node entries in tar archives.
+May 03, 2007: Move 'struct stat' out of archive_entry core as well.
+	This removes some portability headaches and fixes a bunch
+	of corner cases that arise when manipulating archives on
+	dissimilar systems.
+
+Apr 30, 2007: libarchive 2.1.10 released
+Apr 31, 2007: Minor code cleanup.
+
+Apr 24, 2007: libarchive 2.1.9 released
+Apr 24, 2007: Fix some recently-introduced problems with libraries
+	(Just let automake handle it and it all works much better.)
+	Finish isolating major()/minor()/makedev() in archive_entry.c.
+
+Apr 23, 2007: libarchive 2.1.8 released
+Apr 23, 2007: Minor fixes found from building on MacOS X
+
+Apr 22, 2007: libarchive 2.1.7 released
+Apr 22, 2007: Eliminated all uses of 'struct stat' from the
+	format readers/writers.  This should improve portability;
+	'struct stat' is now only used in archive_entry and in
+	code that actually touches the disk.
+
+Apr 17, 2007: libarchive 2.1.6 released
+	Libarchive now compiles and passes all tests on Interix.
+
+Apr 16, 2007: libarchive 2.1.5 released
+
+Apr 15, 2007: libarchive 2.1b2 released
+Apr 15, 2007: New libarchive_internals.3 documentation of internal APIs.
+	Not complete, but should prove helpful.
+Apr 15, 2007: Experimental "read_compress_program" and "write_compress_program"
+	for using libarchive with external compression.  Not yet
+	well tested, and likely has portability issues.  Feedback
+	appreciated.
+
+Apr 14, 2007: libarchive 2.0.31 released
+Apr 14, 2007: More fixes for Interix, more 'ar' work
+
+Apr 14, 2007: libarchive 2.0.30 released
+Apr 13, 2007: libarchive now enforces trailing '/' on dirs
+	written to tar archives
+
+Apr 11, 2007: libarchive 2.0.29 released
+Apr 11, 2007: Make it easier to statically configure for different platforms.
+Apr 11, 2007: Updated config.guess, config.sub, libtool
+
+Apr 06, 2007: libarchive 2.0.28 released
+Apr 06, 2007: 'ar' format read/write support thanks to Kai Wang.
+
+Apr 01, 2007: libarchive 2.0.27 released
+Mar 31, 2007: Several minor fixes from Colin Percival and Joerg Sonnenberger.
+
+Mar 12, 2007: libarchive 2.0.25 released
+Mar 12, 2007: Fix broken --unlink flag.
+
+Mar 11, 2007: libarchive 2.0.24 released
+Mar 10, 2007: Correct an ACL blunder that causes any ACL with an entry
+    that refers to a non-existent user or group to not be restored correctly.
+    The fix both makes the parser more tolerant (so that archives created
+    with the buggy ACLs can be read now) and corrects the ACL formatter.
+Mar 10, 2007: More work on test portability to Linux.
+
+Mar 10, 2007: libarchive 2.0.22 released
+Mar 10, 2007: Header cleanups; added linux/fs.h, removed
+    some unnecessary headers, added #include guards in bsdtar.
+    If you see any obvious compile failures from this, let me know.
+Mar 10, 2007: Work on bsdtar test scripts: not yet robust enough
+    to enable as part of "make check", but getting better.
+Mar 10, 2007: libarchive now returns ARCHIVE_FAILED when
+    a header write fails in a way that only affects this item.
+    Less bad than ARCHIVE_FATAL, but worse than ARCHIVE_WARN.
+
+Mar 07, 2007: libarchive 2.0.21 released
+Mar 07, 2007: Add some ACL tests (only for the system-independent
+    portion of the ACL support for now).
+Mar 07, 2007: tar's ability to read ACLs off disk got
+    turned off for FreeBSD; re-enable it.  (ACL restores and
+    libarchive support for storing/reading ACLs from pax
+    archives was unaffected.)
+
+Mar 02, 2007: libarchive 2.0.20 released
+Mar 2, 2007:  It's not perfect, but it's pretty good.
+    Libarchive 2.0 is officially out of beta.
+
+Feb 28, 2007: libarchive 2.0b17 released
+Feb 27, 2007: Make the GID restore checks more robust by checking
+    whether the current user has too few or too many privileges.
+
+Feb 26, 2007: libarchive 2.0b15 released
+Feb 26, 2007: Don't lose symlinks when extracting from ISOs.
+    Thanks to Diego "Flameeyes" Pettenò for telling me about the
+    broken testcase on Gentoo that (finally!) led me to the cause
+    of this long-standing bug.
+
+Feb 26, 2007: libarchive 2.0b14 released
+Feb 26, 2007: Fix a broken test on platforms that lack lchmod().
+
+Feb 25, 2007: libarchive 2.0b13 released
+Feb 25, 2007: Empty archives were being written as empty files,
+    without a proper end-of-archive marker.  Fixed.
+
+Feb 23, 2007: libarchive 2.0b12 released
+Feb 22, 2007: Basic security checks added: _EXTRACT_SECURE_NODOTDOT
+    and _EXTRACT_SECURE_SYMLINK.  These checks used to be in bsdtar,
+    but they belong down in libarchive where they can be used by
+    other tools and where they can be better optimized.
+
+Feb 11, 2007: libarchive 2.0b11 released
+Feb 10, 2007: Fixed a bunch of errors in libarchive's handling
+    of EXTRACT_PERM and EXTRACT_OWNER, especially relating
+    to SUID and SGID bits.
+
+Jan 31, 2007: libarchive 2.0b9 released
+Jan 31, 2007: Added read support for "empty" archives as a
+    distinct archive format.  Bsdtar uses this to handle, e.g.,
+    "touch foo.tar; tar -rf foo.tar"
+
+Jan 22, 2007: libarchive 2.0b6 released
+Jan 22, 2007: archive_write_disk API is now in place.  It provides
+    a finer-grained interface than archive_read_extract.  In particular,
+    you can use it to create objects on disk without having an archive
+    around (just feed it archive_entry objects describing what you
+    want to create), you can override the uname/gname-to-uid/gid lookups
+    (minitar uses this to avoid getpwXXX() and getgrXXX() bloat).
+
+Jan 09, 2007: libarchive 2.0a3 released
+Jan 9, 2007: archive_extract is now much better; it handles the
+    most common cases with a minimal number of system calls.
+    Some features still need a lot of testing, especially corner
+    cases involving objects that already exist on disk.   I expect
+    the next round of API overhaul will simplify building test cases.
+Jan 9, 2007: a number of fixes thanks to Colin Percival, especially
+    corrections to the skip() framework and handling of large files.
+Jan 9, 2007: Fixes for large ISOs.  The code should correctly handle
+    very large ISOs with entries up to 4G.   Thanks to Robert Sciuk
+    for pointing out these issues.
+
+Sep 05, 2006: libarchive 1.3.1 released
+Sep 5, 2006: Bump version to 1.3 for new I/O wrappers.
+Sep 4, 2006: New memory and FILE read/write wrappers.
+Sep 4, 2006: libarchive test harness is now minimally functional;
+    it's located a few minor bugs in error-handling logic
+
+Aug 17, 2006: libarchive 1.2.54 released
+Aug 17, 2006: Outline ABI changes for libarchive 2.0; these
+   are protected behind #ifdef's until I think I've found everything
+   that needs to change.
+Aug 17, 2006: Fix error-handling in archive_read/write_close()
+   They weren't returning any errors before.
+Aug 17, 2006: Fix recursive-add logic to not trigger if it's not set
+   Fixes a bug adding files when writing archive to pipe or when
+   using archive_write_open() directly.
+Jul 2006: New "skip" handling improves performance extracting
+   single files from large uncompressed archives.
+
+Mar 21, 2006: 1.2.52 released
+Mar 21, 2006: Fix -p on platforms that don't have platform-specific
+   extended attribute code.
+Mar 20, 2006: Add NEWS file; fill in some older history from other
+   files.  I'll try to keep this file up-to-date from now on.
+
+OLDER NEWS SUMMARIES
+
+Mar 19, 2006: libarchive 1.2.51 released
+Mar 18, 2006: Many fixes to extended attribute support, including a redesign
+   of the storage format to simplify debugging.
+Mar 12, 2006: Remove 'tp' support; it was a fun idea, but not worth
+   spending much time on.
+Mar 11, 2006: Incorporated Jaakko Heinonen's still-experimental support
+   for extended attributes (Currently Linux-only.).
+Mar 11, 2006: Reorganized distribution package: There is now one tar.gz
+   file that builds both libarchive and bsdtar.
+Feb 13, 2006: Minor bug fixes: correctly read cpio device entries, write
+   Pax attribute entry names.
+Nov 7, 2005: Experimental 'tp' format support in libarchive.  Feedback
+   appreciated; this is not enabled by archive_read_support_format_all()
+   yet as I'm not quite content with the format detection heuristics.
+Nov 7, 2005: Some more portability improvements thanks to Darin Broady,
+   minor bugfixes.
+Oct 12, 2005: Use GNU libtool to build shared libraries on many systems.
+Aug 9, 2005: Correctly detect that MacOS X does not have POSIX ACLs.
+Apr 17, 2005: Kees Zeelenberg has ported libarchive and bsdtar to Windows:
+   http://gnuwin32.sourceforge.net/
+Apr 11, 2005: Extended Zip/Zip64 support thanks to Dan Nelson.  -L/-h
+   fix from Jaakko Heinonen.
+Mar 12, 2005: archive_read_extract can now handle very long
+   pathnames (I've tested with pathnames up to 1MB).
+Mar 12, 2005: Marcus Geiger has written an article about libarchive
+   http://xsnil.antbear.org/2005/02/05/archive-mit-libarchive-verarbeiten/
+   including examples of using it from Objective-C.  His MoinX
+   http://moinx.antbear.org/ desktop Wiki uses
+   libarchive for archiving and restoring Wiki pages.
+Jan 22, 2005: Preliminary ZIP extraction support,
+    new directory-walking code for bsdtar.
+Jan 16, 2005: ISO9660 extraction code added; manpage corrections.
+May 22, 2004: Many gtar-compatible long options have been added; almost
+    all FreeBSD ports extract correctly with bsdtar.
+May 18, 2004: bsdtar can read Solaris, HP-UX, Unixware, star, gtar,
+    and pdtar archives.

+    entries that require pax extensions (for long filenames, ACLs, etc).
+  * Old GNU tar format
+  * POSIX octet-oriented cpio
+  * SVR4 "newc" cpio
+  * shar archives
+  * ZIP archives (with uncompressed or "deflate" compressed entries)
+  * GNU and BSD 'ar' archives
+  * 'mtree' format
+  * ISO9660 format
+  * 7-Zip archives
+  * XAR archives
+
+When creating archives, the result can be filtered with any of the following:
+  * uuencode
+  * gzip compression
+  * bzip2 compression
+  * compress/LZW compression
+  * lzma, lzip, and xz compression
+
+Notes about the library architecture:
+
+ * This is a heavily stream-oriented system.  There is no direct
+   support for in-place modification or random access.
+
+ * The library is designed to be extended with new compression and
+   archive formats.  The only requirement is that the format be
+   readable or writable as a stream and that each archive entry be
+   independent.  There are articles on the libarchive Wiki explaining
+   how to extend libarchive.
+
+ * On read, compression and format are always detected automatically.
+
+ * I've attempted to minimize static link pollution.  If you don't
+   explicitly invoke a particular feature (such as support for a
+   particular compression or format), it won't get pulled in.
+   In particular, if you don't explicitly enable a particular
+   compression or decompression support, you won't need to link
+   against the corresponding compression or decompression libraries.
+   This also reduces the size of statically-linked binaries in
+   environments where that matters.
+
+ * On read, the library accepts whatever blocks you hand it.
+   Your read callback is free to pass the library a byte at a time
+   or mmap the entire archive and give it to the library at once.
+   On write, the library always produces correctly-blocked output.
+
+ * The object-style approach allows you to have multiple archive streams
+   open at once.  bsdtar uses this in its "@archive" extension.
+
+ * The archive itself is read/written using callback functions.
+   You can read an archive directly from an in-memory buffer or
+   write it to a socket, if you wish.  There are some utility
+   functions to provide easy-to-use "open file," etc, capabilities.
+
+ * The read/write APIs are designed to allow individual entries
+   to be read or written to any data source:  You can create
+   a block of data in memory and add it to a tar archive without
+   first writing a temporary file.  You can also read an entry from
+   an archive and write the data directly to a socket.  If you want
+   to read/write entries to disk, there are convenience functions to
+   make this especially easy.
+
+ * Note: "pax interchange format" is really an extended tar format,
+   despite what the name says.

+ * Utility to match up hardlinks.
+ *
+ * The 'struct archive_entry_linkresolver' is a cache of archive entries
+ * for files with multiple links.  Here's how to use it:
+ *   1. Create a lookup object with archive_entry_linkresolver_new()
+ *   2. Tell it the archive format you're using.
+ *   3. Hand each archive_entry to archive_entry_linkify().
+ *      That function will return 0, 1, or 2 entries that should
+ *      be written.
+ *   4. Call archive_entry_linkify(resolver, NULL) until
+ *      no more entries are returned.
+ *   5. Call archive_entry_linkresolver_free(resolver) to free resources.
+ *
+ * The entries returned have their hardlink and size fields updated
+ * appropriately.  If an entry is passed in that does not refer to
+ * a file with multiple links, it is returned unchanged.  The intention
+ * is that you should be able to simply filter all entries through
+ * this machine.
+ *
+ * To make things more efficient, be sure that each entry has a valid
+ * nlinks value.  The hardlink cache uses this to track when all links
+ * have been found.  If the nlinks value is zero, it will keep every
+ * name in the cache indefinitely, which can use a lot of memory.
+ *
+ * Note that archive_entry_size() is reset to zero if the file
+ * body should not be written to the archive.  Pay attention!
+ */
+struct archive_entry_linkresolver;
+
+/*
+ * There are three different strategies for marking hardlinks.
+ * The descriptions below name them after the best-known
+ * formats that rely on each strategy:
+ *
+ * "Old cpio" is the simplest, it always returns any entry unmodified.
+ *    As far as I know, only cpio formats use this.  Old cpio archives
+ *    store every link with the full body; the onus is on the dearchiver
+ *    to detect and properly link the files as they are restored.
+ * "tar" is also pretty simple; it caches a copy the first time it sees
+ *    any link.  Subsequent appearances are modified to be hardlink
+ *    references to the first one without any body.  Used by all tar
+ *    formats, although the newest tar formats permit the "old cpio" strategy
+ *    as well.  This strategy is very simple for the dearchiver,
+ *    and reasonably straightforward for the archiver.
+ * "new cpio" is trickier.  It stores the body only with the last
+ *    occurrence.  The complication is that we might not
+ *    see every link to a particular file in a single session, so
+ *    there's no easy way to know when we've seen the last occurrence.
+ *    The solution here is to queue one link until we see the next.
+ *    At the end of the session, you can enumerate any remaining
+ *    entries by calling archive_entry_linkify(NULL) and store those
+ *    bodies.  If you have a file with three links l1, l2, and l3,
+ *    you'll get the following behavior if you see all three links:
+ *           linkify(l1) => NULL   (the resolver stores l1 internally)
+ *           linkify(l2) => l1     (resolver stores l2, you write l1)
+ *           linkify(l3) => l2, l3 (all links seen, you can write both).
+ *    If you only see l1 and l2, you'll get this behavior:
+ *           linkify(l1) => NULL
+ *           linkify(l2) => l1
+ *           linkify(NULL) => l2   (at end, you retrieve remaining links)
+ *    As the name suggests, this strategy is used by newer cpio variants.
+ *    It's noticeably more complex for the archiver, slightly more complex
+ *    for the dearchiver than the tar strategy, but makes it straightforward
+ *    to restore a file using any link by simply continuing to scan until
+ *    you see a link that is stored with a body.  In contrast, the tar
+ *    strategy requires you to rescan the archive from the beginning to
+ *    correctly extract an arbitrary link.
