3 Examples
3.1 Start and stop windows and servers
The main process in Reltool is the server. It can be used as it is or be used via the GUI frontend process. When the GUI is started, a server process will automatically be started. The GUI process is started with reltool:start/0, reltool:start/1 or reltool:start_link/1. The pid of its server can be obtained with reltool:get_server/1
