+// A subsystem for managing INI (i.e. .ini) files\r
+// An INI file has the following format\r
+\r
+// file ::= header { section }*\r
+// header ::= { comment | blank }*\r
+// section ::= section_header { declaration | comment | blank }*\r
+// section_header ::= '[' title ']' '\n'\r
+// declaration ::= variable '=' value '\n'\r
+// comment ::= ';' text '\n'\r
+// blank ::= '\n'\r
+// title ::= [~']']*\r
+// variable ::= [~'=']*\r
+// value ::= .*\r
+// text ::= .*\r
+\r
+// Whitespace is trimmed from the leading and trailing ends of title, variable and value\r
+// Note: a header is represented internally as a Clint section (i.e. a section with no name)\r
