/**
 * Install / update EGroupware - Command line interface
 *
 * Usage:
 *
 * - install-cli.php [-v|--verbose] [--use-prerelease] [<composer-args>] [(master|bugfix|release|<branch>|<tag>)]
 *   you can use composer install arguments like: --ignore-platform-reqs --no-dev
 *
 * - install-cli.php [-c|--continue-on-error] --git(-apps) <arguments>
 *   runs git with given arguments (in main- and) all app-dirs, e.g. tag -a 17.1.20190214 -m 'tagging release'
 *
 * EGroupware main directory should be either git cloned:
 *
 *	git clone [-b <branch>] https://github.com/EGroupware/egroupware [<target>]
 *
 * or created via composer create-project
 *
 *	composer create-project --prefer-source --keep-vcs egroupware/egroupware[:(dev-master|17.1.x-dev|<tag>)] <target>
 *
 * Both will create a git clone, which can be further updated by calling this tool without argument.
 *
 * We currently use 3 "channels":
 * - release: taged maintenance releases only eg. 17.1.20190214
 * - bugfix:  release-branch incl. latest bugfixes eg. 17.1 or 17.1.x-dev for composer
 * - master:  latest development for next release
 * To change the channel, call install-cli.php <channel-to-update-to>.
 *
 * This tool requires the following binaries installed at the usually places or in your path:
 * - php & git: apt/yum/zypper install php-cli git
 * - composer: see https://getcomposer.org/download/ for installation instructions
 * The following binaries are needed to minify JavaScript and CSS
 * - npm: apt/yum/zypper install npm
 * - grunt: npm install -g grunt-cli
