=head1 NAME
genhdlist - generates an hdlist and a synthesis file
=head1 SYNOPSIS
genhdlist [options] dir [dir...]
=head1 OPTIONS
=over 4
=item --dest dir
Build indexes from this directory (that is, chdir's to this directory
before operation).
=item --list
Creates a list file.
=item --md5sum
Generates an MD5SUM file.
=item --nobadrpm
Do not abort on bad rpms.
=item --noclean
Keep cache files.
=item -s
Silent mode.
=item --subdir directory
Write indexes in this subdirectory.
=item --suffix SUFFIX
Put a suffix on list/hdlist/synthesis names (for example, C<_main>).
=back
=head1 DESCRIPTION
F<genhdlist> is used to generate an hdlist and an associated synthesis file
from a set of RPM packages found in the directories passed on the command-line.
By default it will put the hdlist and synthesis files in the current directory.
If the option B<--list> is given, it will also generate a F<list> file containing
the relative paths to all RPMs. Consequently, the paths to the directories
passed to F<genhdlist> must be relative ones.
