=head1 NAME

dh_perl_openssl - add dependencies required for OpenSSL modules

=head1 SYNOPSIS

B<dh_perl_openssl> [S<I<debhelper options>>]

=head1 DESCRIPTION

dh_perl_openssl is a debhelper program that is responsible for adding a dependency
on perl-openssl-abi-* to the ${perl:Depends} substitution variable.
Such a dependency is needed for packages that expose the OpenSSL binary
interface to Perl code, such as pointers to C<SSL_CTX> structs.

A debhelper addon is also provided.  This makes it possible to just use

  #!/usr/bin/make -f
  %:
          dh $@ --with perl_openssl

for F<debian/rules>.
