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