B<GNU shtool> is a compilation of small but very stable and portable shell
scripts into a single shell tool. All ingredients were in successful use over
many years in various free software projects. The compiled B<shtool> script is
intended to be used inside the source tree of those free software packages.
There it can take over various (usually non-portable) tasks related to the
building and installation of such packages.

The following I<global options> are available for B<shtool>. Any I<command>s
are ignored if one of them is present on the B<shtool> command line.

=head1 HISTORY

Some scripts contained in GNU B<shtool> were already written in 1994 by
I<Ralf S. Engelschall> for use inside some private source trees. Then
they evolved into more elaborated versions over the years and were used
in various free software projects like ePerl, WML, iSelect, gFONT, etc.
They were complemented with other scripts from the author which he wrote
in March 1998 for the ``Apache Autoconf-style Interface'' (APACI) for
Apache 1.3. In April 1999 the B<shtool> package was created out of the
accumulated master versions of the scripts and in June 1999 it entered
the status of an official GNU program and this way finally joined the
group of GNU B<autoconf>, GNU B<automake> and GNU B<libtool>.
