#   Makefile - Embedthis GoAhead Makefile wrapper for per-platform makefiles
#
#	This Makefile is for Unix/Linux and Cygwin. On windows, it can be invoked via make.bat.
#
#   You can use this Makefile and build via "make" with a pre-selected configuration. Alternatively,
#   you can build using the MakeMe tool for for a fully configurable build. If you wish to
#   cross-compile, you should use MakeMe.
#
#	See projects/$(OS)-$(ARCH)-$(PROFILE)-me.h for configuration default settings. Can override 
#	via make environment variables. For example: make ME_COM_SQLITE=0. These are converted to 
#	DFLAGS and will then override the me.h default values. Use "make help" for a list of available 
#	make variable options.
