# Makerules
#
# Pays attention to the following variables:
#  DEBUG = y      - debugging compiler flags
#  UNAME = xxxxx  - cross-compile for the given platform
#                   (In particular, you can say UNAME = Win32 if mingw
#		     is installed to cross-compile for Windows, or
#		     UNAME = Linux to get 32-bit binaries on Linux x64)
#                   If UNAME undefined on input, gets defined here.
#  DESTDIR = xxxx - Place to put output binaries.
#  MAKERULESDIR   - Where to find Makerules and Makedefs
#
#
# Defines the following variables:
#  UNAME          - destination system type (if not set by user)
#  OBJDIR         - directory for object files
#  CC             - C compiler
#  CXX            - C++ compiler
#  CFLAGS         - C compiler flags
#  CXXFLAGS       - C++ compiler flags
#  LDFLAGS        - Linker flags
#  LIBS           - Libraries
#  GLLIBS         - OpenGL libraries
#  EXE            - Extension of executables (.exe under Win32)
#  LINK           - The entire linking process
#  STATICLIB      - Create .a archive
#  SHAREDLIB      - Create .so archive
#

# Client Makefiles need to define a "default:" rule
# - SMR
