PAC files are now a widely accepted method for proxy configuration management and companies all over are using them in corporate environment. Almost all popular web browsers support PAC files. The idea behind pacparser is to make it easy to add this PAC file parsing capability to any program (C and python supported right now). It comes as a shared C library and a python module which can be used to make any C or python program PAC scripts intelligent. Some very useful targets could be popular web software like wget, curl and python-urllib.
