 Introduction to both programs
 *****************************
 
    GNU `shar' makes so-called shell archives out of many files,
 preparing them for transmission by electronic mail services.  A "shell
 archive" is a collection of files that can be unpacked by `/bin/sh'.  A
 wide range of features provide extensive flexibility in manufacturing
 shars and in specifying shar *smartness*.  For example, `shar' may
 compress files, uuencode binary files, split long files and construct
 multi-part mailings, ensure correct unsharing order, and provide
 simplistic checksums.   shar invocation.
 
    GNU `unshar' scans a set of mail messages looking for the start of
 shell archives.  It will automatically strip off the mail headers and
 other introductory text.  The archive bodies are then unpacked by a
 copy of the shell.  `unshar' may also process files containing
 concatenated shell archives.   unshar invocation.
 
    GNU `shar' has a long history.  All along this long road, numerous
 users contributed various improvements.  The file `THANKS', from the
 GNU `shar' distribution, contain all names still having valid email
 addresses, as far as we know.
 
    Please help me getting the history straight, for the following
 information is approximative.  James Gosling wrote the public domain
 `shar 1.x'.  William Davidsen rewrote it as `shar 2.x'.  Warren Tucker
 brought modifications and called it `shar 3.x'.  Richard Gumpertz
 maintained it until 1990.  Franc,ois Pinard, from the public domain
 `shar 3.49', made `GNU shar 4.x', in 1994.  Some modules and other code
 sections were freely borrowed from other GNU distributions, bringing
 this `shar' under the terms of the GNU General Public License.
