+/*
+ boosty is a wrapper around boost so that OpenSCAD can work with old
+ versions of boost found on popular versions of linux, circa early 2012.
+
+ design
+  hope that the user is compiling with boost>1.46 + filesystem v3
+  if not, fall back to older deprecated functions, and rely on
+  testing to find bugs. implement the minimum needed by OpenSCAD and no more.
+  in a few years, this file should be deleted as unnecessary.
