[erlang-questions] Changing environment variables for an application started from boot script

Hi Kiril,

You are right, the variables in the .app file are basically intended  
for startup.

It is possible to change them (with application:set_env/3), but see  
the warnings in the doc.

One alternative and quite nice way to deal with the config issue is  
to make an mnesia table for all the config items, and use  
mnesia:subscribe to notify users of the config about changes.
