# Module `pl.config`

Reads configuration files into a Lua table.

Understands INI files, classic Unix config files, and simple delimited columns of values. See the Guide

    # test.config
    # Read timeout in seconds
    read.timeout=10
    # Write timeout in seconds
    write.timeout=5
    #acceptable ports
    ports = 1002,1003,1004

    -- readconfig.lua
    local config = require 'config'
    local t = config.read 'test.config'
    print(pretty.write(t))

    ### output #####
    {
      ports = {
        1002,
        1003,
        1004
      },
      write_timeout = 5,
      read_timeout = 10
    }
