################################################################################
# Master one liner interaction with deploying files
#
# Build the assets, then add and commit the files to git
# Then uploads the current branch to the live site, staging site and to GitLab
#
# USAGE:
# Default usage  - ./scripts/deploy/build.sh
#                  
#                  This will add and commit files to git with the message
#                  Committing changes, and then push the changes to gitlab and
#                  staging
#
# Remove push    - ./scripts/deploy/build.sh -g -s
#                  
#                  There are two flags with which you can stop pushing to
#                  their respective remotes
#
#                  -g means don't push to gitlab
#                  -s means don't push to staging
#
# Deploy to live - ./scripts/deploy/build.sh -l
#                  
#                  This is the same behaviour as the default, except it will
#                  also push to the live site
#
# Build assets   - ./scripts/deploy/build.sh -b
#                  
#                  This is the same behaviour as the default, except it will
#                  also run the builder (normally gulp) before adding the files
#                  to git
#
# Custom Message - ./scripts/deploy/build.sh -m "Custom message"
#                  
#                  This is the same behaviour as the default, except it will
#                  also add a custom git commit message instead of the default
#
# Note: all these flags are combinable, example below with every flag
#
#       ./scripts/deploy/build.sh -b -m "Custom message" -gsl
#
# Note: If dotfiles are installed, you can also run a command instead of
#
#       ./scripts/deploy/build.sh
#
#       which is as follows:
#
#       t deploy build

This is the contents of the _config.sh file

git config remote.origin.url  >/dev/null || git remote add origin  <origingitrepo>
git config remote.staging.url >/dev/null || git remote add staging <staginggitrepo>
git config remote.live.url    >/dev/null || git remote add live    <livegitrepo>

Where <origingitrepo> <staginggitrepo> and <livegitrepo> are the remote urls for the git repo in the corresponding place
