-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-01-20 Ben Wing <ben@xemacs.org>
* lrecord.h:
* lrecord.h (enum lrecord_type):
* lrecord.h (struct lrecord_implementation):
Clean up description of finalizer methods. Clean up and expand
the long comment at the top of lrecord.h. Add a section about why
New-GC requires a bunch of new internal objects to be created (not
completely understood).
