go-template

#! /usr/bin/env bash
#
# Template for a Bash program based on the go-script-bash framework
#
# You should replace this comment with your own program's high-level
# description. You may remove any other comments from this template as well.
#
# This template automatically checks for the presence of the go-script-bash
# sources and makes a shallow clone of the the go-script-bash repository if
# necessary before dispatching commands. (If you prefer, you can change the
# logic to create a regular clone instead.) This allows users to set up the
# framework without taking any extra steps when running the command for the
# first time, without the need to commit the framework to your repository.
#
# Alternatively, you can make the `GO_SCRIPT_BASH_REPO_URL` a Git submodule of
# your project or check in a versioned copy of the sources. See the "How to use
# this framework" section of `README.md` for details.
#
# Make sure the variables within this script are configured as necessary for
# your program. You can add any other initialization or configuration between:
#
#   . "$_GO_SCRIPT_BASH_CORE_DIR/go-core.bash" "$GO_SCRIPTS_DIR"`
#   `@go "$@"`

# Set to 'true' if your script is a standalone program, i.e. not bound to
# execute only from the directory in which it resides. See the "Standalone mode"
# section in README.md.

# The path where your command scripts reside
#
# For `_GO_STANDALONE` programs and plugins containing command scripts, you may
# wish to set GO_SCRIPTS_DIR to `bin` and have a separate `./go` script to
# manage project tasks that finds its command scripts in `scripts`.
