#!/bin/bash
# DESCRIPTION
#       for build JBake project on Netlify
#
# USAGE
#       Assume the root directory of your git repository is the root
#       directory of your JBake project.
#       On Netlify, set `Build Cmd` to `sh build.sh [JBake_version]`,
#       then Netlify will build your JBake project with the JBake version
#       you specified. 
#
#       For example, if you want to build the project with JBake v2.4.0,
#       just set `sh build.sh 2.4.0` in `Build Cmd`.
#       
#       If you don't specify the version number, i.e. `sh build.sh`, 
#       then the latest JBake version is used.
#
if [ $# -eq 0 ]
then # if no argument passed in, set jBake to latest version
    jbake_version=2.6.7
else
    jbake_version=$1
