+/* Lots of system calls are trivial functions, so we build their source files
+   from a template.  New syscalls can be added simply by editing the
+   Makefile!
+
+   The system calls aren't necessarily reentrant.  If we were being used in
+   an embedded system they could be.  Reentrant syscalls are also used,
+   however, to provide ANSI C namespace clean access to the host o/s.
+
+   Usage: Compile this file with "func" set to the name of the syscall.  */
