=head1 NAME
Sys::OsPackage::Driver::RPM - RedHat/Fedora RPM packaging handler for Sys::OsPackage
=head1 VERSION
version 0.4.0
=head1 SYNOPSIS
  my $ospkg = Sys::OsPackage->instance();
  # check if packaging commands exist for this system
  if (not $ospkg->call_pkg_driver(op => "implemented")) {
    return 0;
  }
  # find OS package name for Perl module
  my $pkgname = $ospkg->call_pkg_driver(op => "find", module => $module);
  # install a Perl module as an OS package
  my $result1 = $ospkg->call_pkg_driver(op => "modpkg", module => $module);
  # install an OS package
  my $result2 = $ospkg->call_pkg_driver(op => "install", pkg => $pkgname);
=head1 DESCRIPTION
⛔ This is for Sys::OsPackage internal use only.
The Sys::OsPackage method call_pkg_driver() will call the correct driver for the running platform.
The driver implements these methods: I<pkgcmd>, I<modpkg>, I<find>, I<install>, I<is_installed> and I<ping>.
