Makefile for copying a folder to the gh-pages branch
Inspired by the node package of the same name.
To use, create a Makefile, add definitions for the various GHP_* variables, and then include this gh-pages.Makefile.
Example Makefile:
GHP_SRC=build
GHP_DEST=docs
include gh-pages.Makefile
# ... other Make rules
Then run make gh-pages
