=head1 NAME

B<shtool fixperm> - B<GNU shtool> file permission fixing command

=head1 SYNOPSIS

B<shtool fixperm>
[B<-v>|B<--verbose>]
[B<-t>|B<--trace>]
I<path>
[I<path> ...]

=head1 DESCRIPTION

B<shtool fixperm> fixes file permissions inside a source tree under
I<path> by cleaning up the permission bits. It determines the cleaned up
permission from the already set bits. It is intended to be run before
a tarball is rolled (usually with B<shtool tarball>) out of a source
tree. The trick is that this is more convenient than having to set the
permissions manually or by using a large file list.

=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.

=head1 HISTORY

Engelschall E<lt>rse@engelschall.comE<gt> in 1996 for I<OSSP eperl>.
It was later taken over into B<GNU shtool>.
