-# This program reads a file containing function prototypes
-# (like syscall_darwin.go) and generates system call bodies.
-# The prototypes are marked by lines beginning with "//sys"
-# and read like func declarations if //sys is replaced by func, but:
-#	* The parameter lists must give a name for each argument.
-#	  This includes return parameters.
-#	* The parameter lists must give a type for each argument:
-#	  the (x, y, z int) shorthand is not allowed.
-#	* If the return parameter is an error number, it must be named errno.
-
-# A line beginning with //sysnb is like //sys, except that the
-# goroutine will not be suspended during the execution of the system
-# call.  This must only be used for system calls which can never
-# block, as otherwise the system call could cause all goroutines to
-# hang.
