+// Package syscall contains an interface to the low-level operating system
+// primitives. The details vary depending on the underlying system, and
+// by default, godoc will display the syscall documentation for the current
+// system. If you want godoc to display syscall documentation for another
+// system, set $GOOS and $GOARCH to the desired system. For example, if
+// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
+// to freebsd and $GOARCH to arm.
+// The primary use of syscall is inside other packages that provide a more
+// portable interface to the system, such as "os", "time" and "net". Use
+// those packages rather than this one if you can.
+// For details of the functions and data types in this package consult
+// the manuals for the appropriate operating system.
+// These calls return err == nil to indicate success; otherwise
+// err is an operating system error describing the failure.
+// On most systems, that error has type syscall.Errno.
+//
+// Deprecated: this package is locked down. Callers should use the
+// corresponding package in the golang.org/x/sys repository instead.
+// That is also where updates required by new systems or versions
+// should be applied. See https://golang.org/s/go1.4-syscall for more
+// information.
