Makefile

#******************************************************************************
#  Free implementation of Bullfrog's Dungeon Keeper strategy game.
#******************************************************************************
#   @file Makefile
#      A script used by GNU Make to recompile the project.
#  @par Purpose:
#      Allows invoking "make all" or similar commands to compile all source
#      files and link them into an executable file.
#  @par Comment:
#      Run make from a POSIX-compatible shell; Windows cmd.exe is not supported.
#      A MinGW-w64 toolchain and coreutils are required to build the project.
#      To prepare a release package, run:
#        make standard && make heavylog && make package
#  @author   Tomasz Lis
