-dnl @synopsis ST_LIB_ARCHIVE([ENABLED-DEFAULT])
-dnl
-dnl This macro figures out what's necessary to link a program against an
-dnl instance of the BSD libarchive package by Tim Kientzle.
-dnl
-dnl See http://people.freebsd.org/~kientzle/libarchive/ for more info.
-dnl
-dnl It exports and substitutes the variables LIBARCHIVE_LIBS, LIBARCHIVE_LDFLAGS,
-dnl and LIBARCHIVE_CPPFLAGS to appropriate values for the identified instance of
-dnl libarchive. The values are AC_SUBST'd, so a user could, for example, simply
-dnl include @LIBARCHIVE_CPPFLAGS@ in the definition of AM_CPPFLAGS in a Makefile.am.
-dnl
-dnl ENABLED-DEFAULT is either "yes" or "no" and determines whether the default value
-dnl is --with-libarchive or --without-libarchive. It is not possible to specify a
-dnl default directory. More simply, any reasonable choice for a default should just
-dnl go into the auto-detect list.
-dnl
-dnl The macro defines the symbol HAVE_LIBARCHIVE if the library is found. You
-dnl should use autoheader to include a definition for this symbol in a config.h
-dnl file. Sample usage in a C/C++ source is as follows:
-dnl
-dnl #ifdef HAVE_LIBARCHIVE
-dnl #include <archive.h>
-dnl #endif /* HAVE_LIBARCHIVE */
-dnl
-dnl @category InstalledPackages
-dnl @author Andre Stechert <andre@splunk.com>

-ODP: [Bug-tar] GNU tar, star and BSD tar speed comparision +new script

-Jan Psota
-Thu, 25 Oct 2007 06:51:13 -0700
-
-Latest TCP script at the bottom (3180 bytes).
-4 tests: 64bit dual core Athlon tmpfs / disk (reiserfs) - 60MB/s,
- 32bit Athlon tmpfs / disk (reiserfs) - 55MB/s
-Both machines were idle -- used for testing only.
-Tarball and extracted files were on different physical devices.
-Test data: linux 2.6.22/3 kernel sources for memory operations,
-for the other data average file size should bring enough info.
-
-2 x [...] processor means 1 processor with 2 cores (2 entries in cpuinfo).
-Archive format is set to pax (Joerg).
-Let's end with it. I only wanted to send You a new version of TCP script :-).

-.Sh NAME
-.Nm shar
-.Nd create a shell archive of files
-.Sh SYNOPSIS
-.Nm
-.Op Fl br
-.Op Fl o Ar archive-file
-.Ar
-.Sh DESCRIPTION
-The
-.Nm
-command writes a
-.Xr sh 1
-shell script which will recreate the file hierarchy specified by the command
-line operands.
-.Pp
-The
-.Nm
-command is normally used for distributing files by
-.Xr ftp 1
-or
-.Xr mail 1 .
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl b
-Use an alternative binary format. Content of files will be uuencoded.
-This option should be used to archive binary files correctly.
-In this mode also file permissions will be stored to the archive.
-uudecode(1) is needed to extract archives created with this option.
-.It Fl o Ar archive-file
-Redirect output to
-.Ar archive-file .
-.It Fl r
-If
-.Ar file
-given on command line is a directory the entire subtree will be archived.
-Symbolic links given on command line are followed. Other symbolic links will
-be archived as such.
-.El
-.Sh EXAMPLES
-To create a shell archive of the program
-.Xr ls 1
-and mail it to Rick:
-.Bd -literal -offset indent
-cd ls
-shar -r . \&| mail -s "ls source" rick
-.Ed
-.Pp
-To recreate the program directory:
-.Bd -literal -offset indent
-mkdir ls
-cd ls
-\&...
-<delete header lines and examine mailed archive>
-\&...
-sh archive
-.Ed
-.Sh SEE ALSO
-.Xr compress 1 ,
-.Xr mail 1 ,
-.Xr tar 1 ,
-.Xr uuencode 1 ,
-.Xr uuencode 5
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.4 .
-This is a re-implementation based on the libarchive(3) library.
-.Sh BUGS
-The
-.Nm
-command makes no provisions for hard links.
-.Pp
-Files containing magic characters or files without a newline ('\\n') as the
-last character are not handled correctly with the default format. Use the -b
-option for binary files.
-.Pp
-It is easy to insert trojan horses into
-.Nm
-files.
-It is strongly recommended that all shell archive files be examined
-before running them through
-.Xr sh 1 .
-Archives produced using this implementation of
-.Nm
-may be easily examined with the command:
-.Bd -literal -offset indent
-egrep -v '^[X#]' shar.file
-.Ed

- * This is a new directory-walking system that addresses a number
- * of problems I've had with fts(3). In particular, it has no
- * pathname-length limits (other than the size of 'int'), handles
- * deep logical traversals, uses considerably less memory, and has
- * an opaque interface (easier to modify in the future).
- *
- * Internally, it keeps a single list of "tree_entry" items that
- * represent filesystem objects that require further attention.
- * Non-directories are not kept in memory: they are pulled from
- * readdir(), returned to the client, then freed as soon as possible.
- * Any directory entry to be traversed gets pushed onto the stack.
- *
- * There is surprisingly little information that needs to be kept for
- * each item on the stack. Just the name, depth (represented here as the
- * string length of the parent directory's pathname), and some markers
- * indicating how to get back to the parent (via chdir("..") for a
- * regular dir or via fchdir(2) for a symlink).

-/*
- * "untar" is an extremely simple tar extractor:
- * * A single C source file, so it should be easy to compile
- * and run on any system with a C compiler.
- * * Extremely portable standard C. The only non-ANSI function
- * used is mkdir().
- * * Reads basic ustar tar archives.
- * * Does not require libarchive or any other special library.
- *
- * To compile: cc -o untar untar.c
- *
- * Usage: untar <archive>
- *
- * In particular, this program should be sufficient to extract the
- * distribution for libarchive, allowing people to bootstrap
- * libarchive on systems that do not already have a tar program.
- *
- * To unpack libarchive-x.y.z.tar.gz:
- * * gunzip libarchive-x.y.z.tar.gz
- * * untar libarchive-x.y.z.tar
- *
- * Written by Tim Kientzle, March 2009.
- *
- * Released into the public domain.
