This page has the most up-to-date Core Erlang specification, <BR>
and some info on how to compile to/from Core source code: <BR>
<BR>
http://www.it.uu.se/research/group/hipe/cerl/ <BR>
<BR>
The Core Erlang representation is an important intermediate <BR>
step for the BEAM compiler, and the HiPE compiler can generate <BR>
native code directly from Core Erlang as well as from BEAM. <BR>
