# Update the freebsd.xml file.

# FreeBSD uses the same list of system calls on all architectures.
# The list is defined in the sys/kern/syscalls.master file in the
# FreeBSD source tree.  This file is used as an input to generate
# several files that are also stored in FreeBSD's source tree.  This
# script parses one of those generated files (sys/sys/syscall.h)
# rather than syscalls.master as syscall.h is easier to parse.
