=head1 NAME

fsh-buildsis - A tool that generates SIS files.

=head1 SYNOPSIS

fsh-buildsis <platform> <input_iby_file_name> <output_sis_file_name> [<certificate_file_name> <private_key_file_name>]

options:

  -h (--help)               Display this help page.

  -v (--verbose)            Verbose output.

  -k (--keep-pkg-file)      Don't delete the generated .pkg file.

  -u (--keep-unsigned-sis)  Keep a copy the .SIS file before it is signed.

                            Appends ".unsigned" to the base file name.

=head1 DESCRIPTION

FShell uses pre-processor magic to allow its F<.iby> files to be used by both C<BUILDROM> and C<MAKESIS>. Because C<BUILDROM> runs the pre-processor over any files it reads, this arrangement just works when building ROMs. However, C<MAKESIS> doesn't use the pre-processor. This script is responsible for generating a temporary file that contains suitably pre-processed F<.iby> data. It then runs C<MAKESIS> on this temporary file.

The <platform> argument must be one of gcce or armv5.

=head1 KNOWN BUGS

None known.
