=head1 NAME
dh_pdl - calculates pdl dependencies
=cut

=head1 SYNOPSIS
B<dh_pdl> [S<I<debhelper options>>] [B<-d>] [S<I<library dirs ...>>]
=head1 DESCRIPTION
dh_pdl is a debhelper program that is responsible for generating
the ${pdl:Depends} substitutions and adding them to substvars files.
The program will look at perl scripts and modules in your package,
and will use this information to generate a dependency on pdl or
pdlapi. The dependency will be substituted into your package's control
file wherever you place the token "${pdl:Depends}".
=head1 OPTIONS
=over 4
=item B<-V>
By default, scripts and architecture independent modules don't depend
on any specific version of pdl. The -V option causes the current
version of the pdl package to be specified.
=item I<library dirs>
If your package installs perl modules in non-standard
directories, you can make dh_perl check those directories by passing their
names on the command line. It will only check the vendorlib and vendorarch
directories by default.
