On Gnu/Linux and Unix platforms, we have a set of established packaging systems (apt, rpm, bsd ports etc). However they all address the issue of automated application provision (install->configure->activate) specificaly for operating systems. What's missing is a tool that performs simillar functionality, but aimed at web applications. Which is precisely the intention behind the development of StAc. It is an application deployment framework, built to automate provision of multiple instances of applications, specificaly web applications. It also keeps the record of end users of the applications that it deploys.
