=head1 SYNOPSIS

B<dh_installpam> [S<I<debhelper options>>] [B<--name=>I<name>]

=head1 DESCRIPTION

B<dh_installpam> is a debhelper program that is responsible for installing
files used by PAM into package build directories.

=head1 FILES

=over 4

=item debian/I<package>.pam

Installed into usr/lib/pam.d/I<package> in the package build directory.

Until compatibility level 14 this file was installed under
etc/pam.d/I<package>. Please consider using the "rm_conffile" feature from
L<dh_installdeb(1)> to ensure the proper removal of previous PAM files.

=head1 OPTIONS

=over 4

=item B<--name=>I<name>

Look for files named debian/I<package>.I<name>.pam and install them as
usr/lib/pam.d/I<name>, instead of using the usual files and installing them
using the package name.
