"""
This script helps to trigger builds of branches. To use it you have to install the python-jenkins module. On Fedora
and Ubuntu/Debian, it is available as the ``python3-jenkins`` package::
$ sudo dnf/apt install python3-jenkins
To make it easier to run you may want to create a shell script or an alias. To create an alias, add this to your
``~/.bashrc`` (or ``~/.zshrc``) file and then log out and log back in again (to apply the alias)::
alias ci="python3 /path/to/openlp_root/scripts/jenkins_script.py -u USERNAME -p PASSWORD"
To create a shell script, create the following file in a location in your ``$PATH`` (I called mine ``ci``)::
#!/bin/bash
python3 /path/to/openlp_root/scripts/jenkins_script.py -u USERNAME -p PASSWORD
``USERNAME`` is your Jenkins username, and ``PASSWORD`` is your Jenkins password or personal token.
An older version of this script used to use a shared TOKEN, but this has been replaced with the username and password.
