A library to parse proxy auto-config (PAC) files. Proxy auto-config files are a vastly used proxy configuration method these days. Web browsers can use a PAC file to determine which proxy server to use or whether to go direct for a given URL. PAC files are written in JavaScript and can be programmed to return different proxy methods (e.g. "PROXY proxy1:port; DIRECT") depending upon URL, source IP address, protocol, time of the day etc. PAC files introduce a lot of possibilities. Needless to say, PAC files are now a widely accepted method for proxy configuration management and companies all over are using them in corporate environments. 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). pacparser/pacparser
