aolserver4-core-4.5.1 4.5.1-4 (amd64 binary) in ubuntu karmic

 This is the web engine that powers the mighty America On-Line. It
 is capable of serving a tremendous number of users, and can publish
 hundreds of virtual servers within the same process at the same time.
 .
 It is similar in many respects to Zope, except based largely on Tcl.
 It is multi-threaded, and has a C API that can be used to extend
 its functionality.
 .
 This package contains the basic shared libraries which are useful
 for building add-on modules and are used also by the daemon.
 It does *not* contain the AOLserver daemon, which can be installed
 using aolserver4-daemon package instead.
