Looking through Erlang sources I have found out that there are many ways to 
parse and compile the code. In general way there is transformation like Code 
-> Tokens -> Forms ->...
But functions for these transformations can be found in many modules: 
erl_scan, erl_parse, compile, epp, io - theese are only those that have 
seen. Functions from that modules often do the same work.

What for such variety ?
