+.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
