-; NetBSD COMPAT_IBCS2 system call name/number "master" file.
-; (See syscalls.conf to see what it is processed into.)
-;
-; Fields: number type [type-dependent ...]
-;	number	system call number, must be in order
-;	type	one of STD, OBSOL, UNIMPL, NODEF, NOARGS, or one of
-;		the compatibility options defined in syscalls.conf.
-;
-; types:
-;	STD	always included
-;	OBSOL	obsolete, not included in system
-;	UNIMPL	unimplemented, not included in system
-;	NODEF	included, but don't define the syscall number
-;	NOARGS	included, but don't define the syscall args structure
-;
-; The compat options are defined in the syscalls.conf file, and the
-; compat option name is prefixed to the syscall name.  Other than
-; that, they're like NODEF (for 'compat' options), or STD (for
-; 'libcompat' options).
-;
-; The type-dependent arguments are as follows:
-; For STD, NODEF, NOARGS, and compat syscalls:
-;	{ pseudo-proto } [alias]
-; For other syscalls:
-;	[comment]
-;
-; #ifdef's, etc. may be included, and are copied to the output files.
-; #include's are copied to the syscall switch definition file only.
