A configuration file consists of several section names, which are enclosed in [] brackets. There are several key = value pairs (key-value Pair) below each section, with 0 or more white space characters (spaces or tabs) on either side of the equals sign, and one row for each key value pair. A line that starts with a number is a comment. At the end of each section, there is one or more blank lines, which are rows containing only 0 or more white space characters (spaces or tabs). The last line of the INI file may or may not be followed by a newline character.
