# Downloads and builds golang.
# Does not install godoc, you may want to `go get` that after install.


# To install:
#   sudo tar -C /usr/local -xzfv go1.8.linux-arm7.tar.gz
#   export PATH=$PATH:/usr/local/go/bin

# If you are on a CHIP Pro and don't have room for the archive and it's contents:
#   cat go1.8.linux-arm7.tar.gz | ssh -t [email protected] "tar xzfv - -C ~/"
#   login and move ~/go to /usr/local/
