a8d11dc273
This patch contains two additions to simplenode.runner: 1. Check if vm.args exists in CWD; if so, use it. This makes it easier to start multiple concurrent nodes on a single machine from one rebar-created release (starting each node from its own directory, with its own copy of vm.args and e.g. sys.config, log directory, database directory, etc.) 2. Add the targets start_boot <file> and console_boot <file>. This is used to select a different boot script. The 'setup' application (http://github.com/esl/setup) builds a special boot script for installation (all apps loaded but not started, making it possible to run install hooks with the full code path in place).
