+
+// Typical usage
+// -------------
+// 
+// Given a configuration file "settings.inp":
+//   atoms  = 25
+//   length = 8.0  # nanometers
+//   name = Reece Surcher
+// 
+// Named values are read in various ways, with or without default values:
+//   ConfigFile config( "settings.inp" );
+//   int atoms = config.read<int>( "atoms" );
+//   double length = config.read( "length", 10.0 );
+//   string author, title;
+//   config.readInto( author, "name" );
+//   config.readInto( title, "title", string("Untitled") );
+// 
+// See file example.cpp for more examples.

+// Release notes:
+// v1.0  21 May 1999
+//   + First release
+//   + Template read() access only through non-member readConfigFile()
+//   + ConfigurationFileBool is only built-in helper class
+// 
+// v2.0  3 May 2002
+//   + Shortened name from ConfigurationFile to ConfigFile
+//   + Implemented template member functions
+//   + Changed default comment separator from % to #
+//   + Enabled reading of multiple-line values
+// 
+// v2.1  24 May 2004
+//   + Made template specializations inline to avoid compiler-dependent linkage
+//   + Allowed comments within multiple-line values
+//   + Enabled blank line termination for multiple-line values
+//   + Added optional sentry to detect end of configuration file
+//   + Rewrote messy trimWhitespace() function as elegant trim()
