+//  /mINI/ v0.9.10
+//  An INI file reader and writer for the modern age.
+//
+///////////////////////////////////////////////////////////////////////////////
+//
+//  A tiny utility library for manipulating INI files with a straightforward
+//  API and a minimal footprint. It conforms to the (somewhat) standard INI
+//  format - sections and keys are case insensitive and all leading and
+//  trailing whitespace is ignored. Comments are lines that begin with a
+//  semicolon. Trailing comments are allowed on section lines.
+//
+//  Files are read on demand, upon which data is kept in memory and the file
+//  is closed. This utility supports lazy writing, which only writes changes
+//  and updates to a file and preserves custom formatting and comments. A lazy
+//  write invoked by a write() call will read the output file, find what
+//  changes have been made and update the file accordingly. If you only need to
+//  generate files, use generate() instead. Section and key order is preserved
+//  on read, write and insert.
+//
+///////////////////////////////////////////////////////////////////////////////
+//
+//  /* BASIC USAGE EXAMPLE: */
+//
+//  /* read from file */
+//  mINI::INIFile file("myfile.ini");
+//  mINI::INIStructure ini;
+//  file.read(ini);
+//
+//  /* read value; gets a reference to actual value in the structure.
+//     if key or section don't exist, a new empty value will be created */
+//  std::string& value = ini["section"]["key"];
+//
+//  /* read value safely; gets a copy of value in the structure.
+//     does not alter the structure */
+//  std::string value = ini.get("section").get("key");
+//
+//  /* set or update values */
+//  ini["section"]["key"] = "value";
+//
+//  /* set multiple values */
+//  ini["section2"].set({
+//      {"key1", "value1"},
+//      {"key2", "value2"}
+//  });
+//
+//  /* write updates back to file, preserving comments and formatting */
+//  file.write(ini);
+//
+//  /* or generate a file (overwrites the original) */
+//  file.generate(ini);
