=head1 NAME

B<shtool-tarball> - B<GNU shtool> command for rolling standardized tarballs

=head1 SYNOPSIS

=head1 DESCRIPTION

This command is for rolling input files under I<path> into a
distribution tarballs which can be extracted by tar(1).

The four important aspects of good open source software tarballs are:
(1) unpack into a single top-level directory, (2) top-level directory
corresponds to the tarball filename, (3) tarball files should be sorted
and (4) arbitrary names for file owner and group.

=head1 OPTIONS

The following command line options are available.

=over 4

=item B<-v>, B<--verbose>

Display some processing information.

=item B<-t>, B<--trace>

Enable the output of the essential shell commands which are executed.

=item B<-o>, B<--output> I<tarball>

Output tarball to file I<tarball>.

=item B<-c>, B<--compress> I<prog>

Pipe resulting tarball through compression program I<prog>.

=item B<-d>, B<--directory> I<directory>

Sets the top-level directory into which the tarball unpacks.
By default it is I<tarball> without the trailing C<.tar.*> extension.

=item B<-u>, B<--user> I<user>

The user (owner) of files and directories in the tarball to I<user>.

=item B<-g>, B<--group> I<group>

The group of files and directories in the tarball to I<group>.

=item B<-e>, B<--exclude> I<pattern>

Exclude files and directories matching comma-separated list of
regex I<pattern> from the tarball. Directories are expanded
before the filtering takes place. The default filter pattern is
"C<CVS,\\.cvsignore,\\.svn,\\.[oa]\$>".

=head1 EXAMPLE

#   Makefile.in
 dist:
     ...
     V=`shtool version -d short ...`; \
     shtool tarball -o foobar-$$V.tar.gz -c 'gzip -9' \
                    -u bar -g gnu -e 'CVS,\.cvsignore' .

=head1 HISTORY

The B<GNU shtool> B<tarball> command was originally written by Ralf S.
Engelschall E<lt>rse@engelschall.comE<gt> in 1999 for B<GNU shtool>.

=head1 SEE ALSO

shtool(1), tar(1), compress(1).
