# HG changeset patch
# User Mahlon E. Smith <mahlon@martini.nu>
# Date 1230194146 0
# Node ID e908d309e7ec1a36b00d8d19126733291e01d2fb
# Parent  b1426511fb64f58e035a70845883bc8fe46cac2c
 * It compiles!
 * Removed additional leftover link parser stuff.
 * Removed unused memory allocate/free stuff until I discuss with my
   cohort.  It may be back... it may be left over from linkparser too.  ;)
 * list() works, but cores.  Not sure why yet.  Really, list() should be
   renamed to something sensible, and return instantiated BSD::Jail
   objects to attach() to or get additional info on.
 * Ruby C bindings are way, way fun.  Reminds me how little C I can
   remember with one project a year :)
