[erlang-questions] Best practice to hot update .hrl

definitons from header files get inserted into erl files directly by  
the preprocessor. (i don't think the Erlang runtime has a concept of  
a "header file" – someone please correct me if i'm wrong.)

so you simply (re)compile the modules that make use of the updated  
hrl file and reload them.
