10	* NOTE
11	*************************************************************
12	* These functions, when they are intended to be user-visible,
13	* are documented in perl/lib/BarnOwl.pm. If you add functions
14	* to this file, add the appropriate documentation there!
15	*
16	* If the function is simple enough, we simply define its
17	* entire functionality here in XS. If, however, it needs
18	* complex argument processing or something, we define a
19	* simple version here that takes arguments in as flat a
20	* manner as possible, to simplify the XS code, put it in
21	* BarnOwl::Internal::, and write a perl wrapper in BarnOwl.pm
22	* that munges the arguments as appropriate and calls the
23	* internal version.
