# A simple Makefile that attempts to weave everything together
# for a build.  Basically:
#  * Makes a temporary build directory
#  * Copies itself and build.mak off, hands over to the new Makefile
#  * Downloads the source
#  * Compiles the native, then win32 versions
#  * Takes the libs from native and hooks them into win32
#  * tars it all up and calls it done
