-# This script runs or (given -n) prints suggested commands to generate files for
-# the Architecture/OS specified by the GOARCH and GOOS environment variables.
-# See README.md for more information about how the build system works.
+# The unix package provides access to the raw system call
+# interface of the underlying operating system.  Porting Go to
+# a new architecture/operating system combination requires
+# some manual effort, though there are tools that automate
+# much of the process.  The auto-generated files have names
+# beginning with z.
+#
+# This script runs or (given -n) prints suggested commands to generate z files
+# for the current system.  Running those commands is not automatic.
+# This script is documentation more than anything else.
+#
+# * asm_${GOOS}_${GOARCH}.s
+#
+# This hand-written assembly file implements system call dispatch.
+# There are three entry points:
+#
+# 	func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+# 	func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
+# 	func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+#
+# The first and second are the standard ones; they differ only in
+# how many arguments can be passed to the kernel.
+# The third is for low-level use by the ForkExec wrapper;
+# unlike the first two, it does not call into the scheduler to
+# let it know that a system call is running.
+#
+# * syscall_${GOOS}.go
+#
+# This hand-written Go file implements system calls that need
+# special handling and lists "//sys" comments giving prototypes
+# for ones that can be auto-generated.  Mksyscall reads those
+# comments to generate the stubs.
+#
+# * syscall_${GOOS}_${GOARCH}.go
+#
+# Same as syscall_${GOOS}.go except that it contains code specific
+# to ${GOOS} on one particular architecture.
+#
+# * types_${GOOS}.c
+#
+# This hand-written C file includes standard C headers and then
+# creates typedef or enum names beginning with a dollar sign
+# (use of $ in variable names is a gcc extension).  The hardest
+# part about preparing this file is figuring out which headers to
+# include and which symbols need to be #defined to get the
+# actual data structures that pass through to the kernel system calls.
+# Some C libraries present alternate versions for binary compatibility
+# and translate them on the way in and out of system calls, but
+# there is almost always a #define that can get the real ones.
+# See types_darwin.c and types_linux.c for examples.
+#
+# * zerror_${GOOS}_${GOARCH}.go
+#
+# This machine-generated file defines the system's error numbers,
+# error strings, and signal numbers.  The generator is "mkerrors.sh".
+# Usually no arguments are needed, but mkerrors.sh will pass its
+# arguments on to godefs.
+#
+# * zsyscall_${GOOS}_${GOARCH}.go
+#
+# Generated by mksyscall.pl; see syscall_${GOOS}.go above.
+#
+# * zsysnum_${GOOS}_${GOARCH}.go
+#
+# Generated by mksysnum_${GOOS}.
+#
+# * ztypes_${GOOS}_${GOARCH}.go
+#
+# Generated by godefs; see types_${GOOS}.c above.
