+%% start_link/4,5 --
+%%
+%% The start/4,5 functions are used to start a slave Erlang node.
+%% The node on which the start/N functions are used is called the
+%% master in the description below.
+%%
+%% If hostname is the same for the master and the slave,
+%% the Erlang node will simply be spawned.  The only requirment for
+%% this to work is that the 'erl' program can be found in PATH.
+%%
+%% If the master and slave are on different hosts, start/N uses
+%% the 'rsh' program to spawn an Erlang node on the other host.
+%% Alternative, if the master was started as
+%% 'erl -sname xxx -rsh my_rsh...', then 'my_rsh' will be used instead
+%% of 'rsh' (this is useful for systems where the rsh program is named
+%% 'remsh').
+%%
+%% For this to work, the following conditions must be fulfilled:
+%%
+%% 1. There must be an Rsh program on computer; if not an error
+%%    is returned.
+%%
+%% 2. The hosts must be configured to allowed 'rsh' access without
+%%    prompts for password.
+%%
+%% The slave node will have its filer and user server redirected
+%% to the master.  When the master node dies, the slave node will
+%% terminate.  For the start_link functions, the slave node will
+%% terminate also if the process which called start_link terminates.
