18  * Compatibility goo for other OS's.  These files are intended to add
19  * support for various FEATURES that other OS's do not support.  Kinda'
20  * like what autoconf is supposed to do, but doesn't.
21  *
22  * These files consist of the following:
23  *
24  *    compat.h       This file, which contains the main feature-goo, along
25  *                   with any OS specific goo.  See below for details.
26  *
27  *    compat.c       The counterpart to this file, which includes all the
28  *                   necessary #includes of compat/ stuff to add various
29  *                   features.
30  *
31  *    compat/        The directory containing all OpenBSD-specific
32  *                   features of vitunes that may be needed on other OS's.
