+// Section is the representation of a section inside git configuration files.
+// Each Section contains Options that are used by both the Git plumbing
+// and the porcelains.
+// Sections can be further divided into subsections. To begin a subsection
+// put its name in double quotes, separated by space from the section name,
+// in the section header, like in the example below:
+//
+//     [section "subsection"]
+//
+// All the other lines (and the remainder of the line after the section header)
+// are recognized as option variables, in the form "name = value" (or just name,
+// which is a short-hand to say that the variable is the boolean "true").
+// The variable names are case-insensitive, allow only alphanumeric characters
+// and -, and must start with an alphabetic character:
+//
+//     [section "subsection1"]
+//         option1 = value1
+//         option2
+//     [section "subsection2"]
+//         option3 = value2
+//
