iniparse.min.lua

--[==[
  This lib provides two functions:
    * load_file(file) -- parses an ini file and returns a table
    * parse(data) -- parses string data in ini format and returns a table
  A few notes: iniparse will allow ; and # style comments, it does not allow duplicate sections and it will overwrite
  duplicate keys/values with the last given key/value pair.
