2   INI configuration parsing library.
3 
4   The INI file format is:
5     ================
6     [SectionName]
7     EntryName=EntryValue
8     ================
9 
10     Where:
11       1) SectionName is an ASCII string. The valid format is [A-Za-z0-9_]+
12       2) EntryName is an ASCII string. The valid format is [A-Za-z0-9_]+
13       3) EntryValue can be:
14          3.1) an ASCII String. The valid format is [A-Za-z0-9_]+
15          3.2) a GUID. The valid format is xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where x is [A-Fa-f0-9]
16          3.3) a decimal value. The valid format is [0-9]+
17          3.4) a heximal value. The valid format is 0x[A-Fa-f0-9]+
18       4) '#' or ';' can be used as comment at anywhere.
19       5) TAB(0x20) or SPACE(0x9) can be used as separator.
20       6) LF(\n, 0xA) or CR(\r, 0xD) can be used as line break.
