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