Makefile: for non-gophers
Many people need or want to build go-ethereum from the git repository, mostly to stay up to date with recent changes. We cannot expect that people without Go experience grok the Go workspace concept. With the Makefile, building from github requires only three steps (provided that a Go toolchain is installed): - git clone https://github.com/ethereum/go-ethereum - ... install C libraries (libgmp, etc.) ... - make
