=head1 NAME

OpenFrame::Example::ApacheSimple - Demo Apache Pipeline

=head1 SYNOPSIS

  SetHandler  perl-script
  PerlSetVar  cwd /home/website/
  # PerlSetVar  debug 1
  PerlHandler OpenFrame::Example::ApacheSimple

=head1 DESCRIPTION

OpenFrame::Example::ApacheSimple is an example pipeline which loads
static content.

The actual handler is quite short. The important part is to set up a
pipeline which has a OpenFrame::Segment::Apache::Request segment at
the beginning and a OpenFrame::Segment::Apache::Response as a cleanup
segment. Also, remember to check for an ofDECLINE and return DECLINED
in that case, or OK otherwise.
