From 54cd1545ff312c40a38cc8707bc73fe5cb0554d5 Mon Sep 17 00:00:00 2001
From: "W. Trevor King" <wking@drexel.edu>

Subject: [PATCH] Add Alias('asymptote-figures') for explicit \asyfig
 dependencies.

Also:
  * Use env.Alias and env.Depends vs. the bare SCons.Script forms.
  * Add figures/cantilever-sim/loading-rate.asy back to build tree.
