=head1 NAME
SystemInstaller::Package::RpmNoScripts - Rpm package installation functions.
=head1 DESCRIPTION
This module provides the SystemInstall package API functions for Rpm based
installation. This module runs the post scriptlets after the installation of
all files to circumvent some limitations. It can only be used with versions of
rpm that support the --nopost flag (4.0.3+).
This module provides the following API subroutines:
files_install.
See the SystemInstaller::Package manpage for details
on the API specification.
