apache2.2-common 2.2.16-4ubuntu1 (i386 binary) in ubuntu natty

 The Apache Software Foundation's goal is to build a secure, efficient and
 extensible HTTP server as standards-compliant open source software. The

 This package contains the configuration and support scripts.
 However, it does *not* include the server itself; for this you need to
 install one of the apache2-mpm-* packages, such as worker or prefork.
