+// Purpose: Simple recursive data access class
+// Used in vgui for message parameters and resource files
+// Destructor deletes all child KeyValues nodes
+// Data is stored in key (string names) - (string/int/float)value pairs called nodes.
+//
+// About KeyValues Text File Format:
+
+// It has 3 control characters '{', '}' and '"'. Names and values may be quoted or
+// not. The quote '"' character must not be used within name or values, only for
+// quoting whole tokens. You may use escape sequences wile parsing and add within a
+// quoted token a \" to add quotes within your name or token. When using Escape
+// Sequence the parser must now that by setting KeyValues::UsesEscapeSequences( true ),
+// which it's off by default. Non-quoted tokens ends with a whitespace, '{', '}' and '"'.
+// So you may use '{' and '}' within quoted tokens, but not for non-quoted tokens.
+// An open bracket '{' after a key name indicates a list of subkeys which is finished
+// with a closing bracket '}'. Subkeys use the same definitions recursively.
+// Whitespaces are space, return, newline and tabulator. Allowed Escape sequences
+// are \n, \t, \\, \n and \". The number character '#' is used for macro purposes
+// (eg #include), don't use it as first character in key names.
