+/*
+
+The bu_vls_vprintf function aims to adhere to the following
+specifications:
+
+ 1. First, follow the UNIX man page at
+ "http://www.unix.com/man-page/POSIX/3/printf/"; regarding the
+ definition of a format specifier.
+
+ 2. Then modify [1] to accomodate a compatible subset of parts
+ applicable to a wide range of standard C libraries including
+ GNU/Linux, Windows, FreeBSD, and others as differences are
+ brought to our attention.
+
+ 3. The subset [2] shall be the "valid" flags, length modifers, and
+ conversion specifiers ("parts") accepted by this function.
+
+ 4. Parts known to be defined outside subset [3] shall generate a
+ message stating such invalidity and giving a suitable
+ alternative if possible (such parts will be called "obsolete");
+ otherwise, the part shall be said to be "unsupported." Any part
+ of either category will then generate a bu_bomb.
+
+ 5. Parts seen by this function but not defined above shall be
+ deemed "unknown" and result in a suitable message followed by a
+ bu_bomb.
