%% ARCHITECTURE
%% The coverage tool consists of one process on each node involved in
%% coverage analysis. The process is registered as 'cover_server'
-%% (?SERVER). All cover_servers in the distributed system are linked
-%% together. The cover_server on the 'main' node is in charge, and it
-%% traps exits so it can detect nodedown or process crashes on the
-%% remote nodes. This process is implemented by the functions
-%% init_main/1 and main_process_loop/1. The cover_server on the remote
-%% nodes are implemented by the functions init_remote/2 and
+%% (?SERVER). The cover_server on the 'main' node is in charge, and
+%% it monitors the cover_servers on all remote nodes. When it gets a
+%% 'DOWN' message for another cover_server, it marks the node as
+%% 'lost'. If a nodeup is received for a lost node the main node
+%% ensures that the cover compiled modules are loaded again. If the
+%% remote node was alive during the disconnected periode, cover data
+%% for this periode will also be included in the analysis.
