+%description
+The Apache HTTP Server is a powerful, efficient, and extensible web server.
+
+This package contain mpm-itk which is an MPM (Multi-Processing Module) for the
+Apache web server. Mpm-itk allows you to run each of your vhost under a separate
+uid and gid — in short, the scripts and configuration files for one vhost no
+longer have to be readable for all the other vhosts.
+
+In summary it is Apache module (opposite CGI solutions like suexec), fast and
+allow safely use non-thread-aware code software (like many PHP extensions f.e.)

+- Initial spec. Based on httpd.spec in Fedora rawhide. Joe Orton has asked

+ he dismiss enhancment request. After that he was asked (with proposed
+ patch) to provide httpd-source package he also dismiss it (BUG#597772).
+ Pride is a mortal sin. But I can not get it to do something.
+ So, instead just base on always current version of Fedora httpd, I have to
+ do it again from begining and doubling... I'll try it do as best as
+ possible in this situation.
