+	UsageLine: "build [-o output] [build flags] [packages]",
+	Short:     "compile and install packages and dependencies",
+	Long: `
+Build compiles the packages named by the import paths,
+along with their dependencies, but it does not install the results.
+
+If the arguments are a list of .go files, build treats them as a list
+of source files specifying a single package.
+
+When the command line specifies a single main package,
+build writes the resulting executable to output.
+Otherwise build compiles the packages but discards the results,
+serving only as a check that the packages can be built.
+
+The -o flag specifies the output file name. If not specified, the
+output file name depends on the arguments and derives from the name
+of the package, such as p.a for package p, unless p is 'main'. If
+the package is main and file names are provided, the file name
+derives from the first file name mentioned, such as f1 for 'go build
+f1.go f2.go'; with no files provided ('go build'), the output file7
+name is the base name of the containing directory.
+
+The build flags are shared by the build, install, run, and test commands:
+
+	-a
+		force rebuilding of packages that are already up-to-date.
+	-n
+		print the commands but do not run them.
+	-p n
+		the number of builds that can be run in parallel.
+		The default is the number of CPUs available.
+	-race
+		enable data race detection.
+		Supported only on linux/amd64, darwin/amd64 and windows/amd64.
+	-v
+		print the names of packages as they are compiled.
+	-work
+		print the name of the temporary work directory and
+		do not delete it when exiting.
+	-x
+		print the commands.
+
+	-ccflags 'arg list'
+		arguments to pass on each 5c, 6c, or 8c compiler invocation.
+	-compiler name
+		name of compiler to use, as in runtime.Compiler (gccgo or gc).
+	-gccgoflags 'arg list'
+		arguments to pass on each gccgo compiler/linker invocation.
+	-gcflags 'arg list'
+		arguments to pass on each 5g, 6g, or 8g compiler invocation.
+	-installsuffix suffix
+		a suffix to use in the name of the package installation directory,
+		in order to keep output separate from default builds.
+		If using the -race flag, the install suffix is automatically set to race
+		or, if set explicitly, has _race appended to it.
+	-ldflags 'flag list'
+		arguments to pass on each 5l, 6l, or 8l linker invocation.
+	-tags 'tag list'
+		a list of build tags to consider satisfied during the build.
+		See the documentation for the go/build package for
+		more information about build tags.
+
+The list flags accept a space-separated list of strings. To embed spaces
+in an element in the list, surround it with either single or double quotes.
+
+For more about specifying packages, see 'go help packages'.
+For more about where packages and binaries are installed,
+see 'go help gopath'.
+
+See also: go install, go get, go clean.
