// This file declares the .res file class. .res files are intermediate
// products of the typical resource-compilation process on Windows. This
// process is as follows:
//
// .rc file(s) ---(rc.exe)---> .res file(s) ---(cvtres.exe)---> COFF file
//
// .rc files are human-readable scripts that list all resources a program uses.
//
// They are compiled into .res files, which are a list of the resources in
// binary form.
//
// Finally the data stored in the .res is compiled into a COFF file, where it
// is organized in a directory tree structure for optimized access by the
// program during runtime.
