#                  OpenPetra Installer Script
#
#   Homepage: https://www.openpetra.org
#   Issues:   https://github.com/openpetra/getopenpetra/issues
#   Requires: bash, curl, sudo (if not root), tar
#
# This script installs OpenPetra on your Linux system.
# You have various options, to install a development environment, or to 
# install a test environment, or to install a production environment.
#
#	$ curl https://getopenpetra.com | bash -s devenv
#	 or
#	$ wget -qO- https://getopenpetra.com | bash -s devenv
#
# The syntax is:
#
#	bash -s [devenv|test|demo|prod]
#
# available options:
#     --git_url=<http git url>
#            default is: --git_url=https://github.com/openpetra/openpetra.git
#     --branch=<branchname>
#            default is: --branch=test
#     --dbms=<dbms>
#            default is: --dbms=mysql
#            other options: postgresql
#     --url=<outside url>
#            default is: --url=http://localhost
#            for demo: --url=https://demo.openpetra.org
#     --emaildomain=<your email domain, used for noreply sender address>
#            default is: --emaildomain=myexample.org
#            for demo: --emaildomain=openpetra.org
#     --instance=<instance>
#            default is: --instance=op_dev for devenv, --instance=op_test for test
#
# If you purchased a commercial license, you must set your account
# ID and API key in environment variables:
#
#	$ export OPENPETRA_ACCOUNT_ID=...
#	$ export OPENPETRA_API_KEY=...
#
# Then you can request a commercially-licensed download:
#
#	$ curl https://getopenpetra.com | bash -s prod
#
# This should work on CentOS 7 and Fedora 31,
# and Ubuntu 19.10 (Eoan Ermine), Ubuntu 18.04 (Bionic Beaver)
# and Debian 10 (Buster).
# Please open an issue if you notice any bugs.
