An encapsulation of a convention I have been using with the slop, nenv, inifile and configatron gems for quick and dirty development of command-line based utility programs. Slop parses ARGV; Nenv parses ENV; inifile parses INI; Configatron keeps it all together. YAML and ERB preprocessing is also available. Ruby configuration files are also supported. and you can specify multiple config files of mixed types at once.
