2.2.1 unshar help/usage (`--help')
----------------------------------

This is the automatically generated usage text for unshar.

   The text printed is the same whether selected with the `help' option
(`--help') or the `more-help' option (`--more-help').  `more-help' will
print the usage text by passing it through a pager program.
`more-help' is disabled on platforms without a working `fork(2)'
function.  The `PAGER' environment variable is used to select the
program, defaulting to `more'.  Both will exit with a status code of 0.

Options are specified by doubled hyphens and their name or by a single
hyphen and the flag character.

If no arguments are provided, input arguments are read from stdin,
one per line; blank and '#'-prefixed lines are comments.
'stdin' may not be a terminal (tty).

The following option preset mechanisms are supported:
 - reading file $HOME/.sharrc

'unshar' scans the input files (typically email messages) looking for the
start of a shell archive.  If no files are given, then standard input is
processed instead.  It then passes each archive discovered through an
invocation of the shell program to unpack it.
