% go help work
Go workspace provides access to operations on workspaces.

Note that support for workspaces is built into many other commands,
not just 'go work'.

See 'go help modules' for information about Go's module system of
which workspaces are a part.

A workspace is specified by a go.work file that specifies a set of
module directories with the "use" directive. These modules are used
as root modules by the go command for builds and related operations.
A workspace that does not specify modules to be used cannot be used
to do builds from local modules.

To determine whether the go command is operating in workspace mode,
use the "go env GOWORK" command. This will specify the workspace
file being used.

Usage:

	go work <command> [arguments]

The commands are:

	edit        edit go.work from tools or scripts
	init        initialize workspace file
	sync        sync workspace build list to modules
	use         add modules to workspace file

Use "go help work <command>" for more information about a command.

% go help work use
usage: go work use [-r] [moddirs]

Use provides a command-line interface for adding directories,
optionally recursively, to a go.work file.

The -r flag searches recursively for modules in the argument directories.
