+From: Anthony G. Basile <blueness@g.o>
+
+The build system searches for <attr/xattr.h> and doesn't bother
+looking to see if setxattr(), getxattr() and friends are provided
+by the system libc.  Worse, on successfully finding <attr/xattr.h>
+it then proceeds to include it but then links against libc for
+the *xattr() functions.
+
+This patch has the build system look for <sys/xattr.h> first and
+if it success, links against libc.  On failing to find <sys/xattr.h>,
+it then search for <attr/xattr.h> and links against libattr.so.  This
+can happen, for instance, on a uClibc system where UCLIBC_HAS_XATTR
+is not set, but libattr.so is present.  Then the *xattr() functions
+must be provided by libattr.so.

+The behavior of tar is controlled by the following environment variables,
+among others:
+.Bl -tag -width Ds
+.It Ev SIMPLE_BACKUP_SUFFIX
+Backup prefix to use when extracting, if
+.Fl \-suffix
+is not specified.
+The backup suffix defaults to `~' if neither is specified.
+.It Ev TAR_OPTIONS
+Options to prepend to those specified on the command line, separated by
+whitespace.  Embedded backslashes may be used to escape whitespace or
+backslashes within an option.
+.It Ev TAPE
+Device or file to use for the archive if 
+.Fl \-file
+is not specified.
+If this environment variable is unset, use stdin or stdout instead.
+.El
+.Sh EXAMPLES
+Create archive.tar from files foo and bar.
+.Bd -literal -offset indent -compact
+tar \-cf archive.tar foo bar
+.Ed
+List all files in archive.tar verbosely.
+.Bd -literal -offset indent -compact
+tar \-tvf archive.tar
+.Ed
+Extract all files from archive.tar.

+.Sh HISTORY
+The

+command appeared in
+.At v7 .
+.Sh BUGS
+The GNU folks, in general, abhor man pages, and create info documents instead.
+Unfortunately, the info document describing tar is licensed under the GFDL with
+invariant cover texts, which makes it impossible to include any text
+from that document in this man page.
+Most of the text in this document was automatically extracted from the usage
+text in the source.
+It may not completely describe all features of the program.
