/*
* This program was originally written long ago, originally for a non
* BSD-like OS without mkstemp(). It's been modified over the years
* to use mkstemp() rather than the original O_CREAT|O_EXCL/fstat/lstat
* etc style hacks.
* A cleanup, misc options and mkdtemp() calls were added to try and work
* more like the OpenBSD version - which was first to publish the interface.
