a bash script that will push a snapshot of your current repo to a remote repository

remoteSnapshot

#!/bin/bash

#This script performs pushes to a remote repo but does not contain the history of the branch
#that it was pushed from. This is useful in the case of consulting work when you want to share
#the current state of a repository but want to obscure the history of the work.
