/*
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>1.44 + filesystem v3
if not, fall back to older deprecated functions, and rely on regression
testing to find bugs. implement the minimum needed by OpenSCAD and no more.
in a few years, this file should be deleted as unnecessary.
