<!--l. 127--><p class="noindent" >This tutorial will build up a sophisticated garbage collector from scratch, starting
with the empty shell that is the NoGC ”collector” in MMTk (collector is a
misnomer in this case since NoGC does not collect), and gradually adding
functionality.
</p><!--l. 129--><p class="noindent" >This tutorial will tell you the mechanics of building a collector in MMTk. It will tell
you how but it does not tell you anything about why. The tutorial thus serves two
purposes: 1) to give you some insight into the mechanics of MMTk (but not the
underlying reasons or design rationale), and 2) show you that the mechanics of
building a non-trivial GC in MMTk is not hard, hopefully giving you conﬁdence to
start exploring MMTk more deeply.
</p><!--l. 131--><p class="noindent" >Please use the latest release to work with the tutorial. If you run into trouble
following the instructions, please try again with <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">git HEAD</span></span></span>. If the problem persists,
please <a
