Each individual file in this distribution should have a clear
copyright/licensing statement at the beginning of the file. If any do
not, please let me know and I will rectify it. The following is
intended to summarize the copyright status of the individual files;

* The build files---including Makefiles, configure scripts,
and auxiliary scripts used as part of the compile process---have
widely varying licensing terms. Please check individual files before
distributing them to see if those restrictions apply to you.
I intend for all new source code to use the license below and hope over
time to replace code with other licenses with new implementations that
do use the license below. The varying licensing of the build scripts
seems to be an unavoidable mess.

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 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.
See the libarchive Wiki or the cmake site for further documentation.

README for libarchive bundle.
Questions? Issues?
* http://libarchive.googlecode.com/ is the home for ongoing
libarchive development, including issue tracker, additional
documentation, and links to the libarchive mailing lists.
This distribution bundle includes the following components:
* libarchive: a library for reading and writing streaming archives
* tar: the 'bsdtar' program is a full-featured 'tar'
replacement built on libarchive
* cpio: the 'bsdcpio' program is a different interface to
essentially the same functionality
* examples: Some small example programs that you may find useful.
* examples/minitar: a compact sample demonstrating use of libarchive.
I use this for testing link pollution; it should produce a very
small executable file on most systems.
* contrib: Various items sent to me by third parties;
please contact the authors with any questions.
The top-level directory contains the following information files:
* NEWS - highlights of recent changes
* COPYING - what you can do with this
* INSTALL - installation instructions
* README - this file
* configure - configuration script, see INSTALL for details.
* CMakeLists.txt - input for "cmake" build tool, see INSTALL
The following files in the top-level directory are used by the
'configure' script:
* Makefile.am, aclocal.m4, configure.ac
- used to build this distribution, only needed by maintainers
* Makefile.in, config.h.in
- templates used by configure script
Guide to Documentation installed by this system:
* bsdtar.1 explains the use of the bsdtar program
* bsdcpio.1 explains the use of the bsdcpio program
* libarchive.3 gives an overview of the library as a whole
* archive_read.3, archive_write.3, archive_write_disk.3, and
archive_read_disk.3 provide detailed calling sequences for the read
and write APIs
* archive_entry.3 details the "struct archive_entry" utility class
* archive_internals.3 provides some insight into libarchive's
internal structure and operation.
* libarchive-formats.5 documents the file formats supported by the library
* cpio.5, mtree.5, and tar.5 provide detailed information about these
popular archive formats, including hard-to-find details about
modern cpio and tar variants.
The manual pages above are provided in the 'doc' directory in
a number of different formats.
You should also read the copious comments in "archive.h" and the
source code for the sample programs for more details. Please let me
know about any errors or omissions you find.
Currently, the library automatically detects and reads the following:
* gzip compression
* bzip2 compression
* compress/LZW compression
* lzma and xz compression
* GNU tar format (including GNU long filenames, long link names, and
sparse files)
* Solaris 9 extended tar format (including ACLs)
* Old V7 tar archives
* POSIX ustar
* POSIX pax interchange format
* POSIX octet-oriented cpio
* SVR4 ASCII cpio
* POSIX octet-oriented cpio
* Binary cpio (big-endian or little-endian)
* ISO9660 CD-ROM images (with optional Rockridge or Joliet extensions)
* ZIP archives (with uncompressed or "deflate" compressed entries)
* GNU and BSD 'ar' archives
* 'mtree' format
The library can write:
* gzip compression
* bzip2 compression
* compress/LZW compression
* lzma and xz compression
* POSIX ustar
* POSIX pax interchange format
* "restricted" pax format, which will create ustar archives except for
entries that require pax extensions (for long filenames, ACLs, etc).
* POSIX octet-oriented cpio
* SVR4 "newc" cpio
* shar archives
* ZIP archives (with uncompressed or "deflate" compressed entries)
* GNU and BSD 'ar' archives
* 'mtree' format
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.
