+# This file provides:
+# - a default control flow
+#   * initializes the environment
+#   * able to mock "git push" in your script and in all sub scripts
+#   * call a function in your script based on the arguments
+# - named argument parsing and automatic generation of the "usage" for your script
+# - intercepting "git push" in your script and all sub scripts
+# - utility functions
+#
+# Usage:
+# - define the variable ARGS_DEF (see below) with the arguments for your script
+# - include this file using `source utils.inc` at the end of your script.
+#
+# Default control flow:
+# 0. Set the current directory to the directory of the script. By this
+#    the script can be called from anywhere.
+# 1. Parse the named arguments
+# 2. If the parameter "git_push_dryrun" is set, all calls to `git push` in this script
+#    or in child scripts will be intercepted so that the `--dry-run` and `--porcelain` is added
+#    to show what the push would do but not actually do it.
+# 3. If the parameter "verbose" is set, the `-x` flag will be set in bash.
+# 4. The function "init" will be called if it exists
+# 5. If the parameter "action" is set, it will call the function with the name of that parameter.
+#    Otherwise the function "run" will be called.
+#
+# Named Argument Parsing:
+# - The variable ARGS_DEF defines the valid command arguments
+#   * Required args syntax: --paramName=paramRegex
+#   * Optional args syntax: [--paramName=paramRegex]
+#   * e.g. ARG_DEFS=("--required_param=(.+)" "[--optional_param=(.+)]")
+# - Checks that:
+#   * all arguments match to an entry in ARGS_DEF
+#   * all required arguments are present
+#   * all arguments match their regex
+# - Afterwards, every parameter value will be stored in a variable
+#   with the name of the parameter in upper case (with dash converted to underscore).
+#
+# Special arguments that are always available:
+# - "--action=.*": This parameter will be used to execute a function with that name when the
+#   script is started
+# - "--git_push_dryrun=true": This will intercept all calls to `git push` in this script
+#   or in child scripts so that the `--dry-run` and `--porcelain` is added
+#   to show what the push would do but not actually do it.
+# - "--verbose=true": This will set the `-x` flag in bash so that all calls will be logged
+#
+# Utility functions:
+# - readJsonProp
+# - replaceJsonProp
+# - resolveDir
+# - getVar
+# - serVar
+# - isFunction
+
+# always stop on errors
