Static usage

usage: Usage = Command.Usage({category: `Workspace-related commands`,description: `run a command on all workspaces`,details: `This command will run a given sub-command on current and all its descendant workspaces. Various flags can alter the exact behavior of the command:- If \`-p,--parallel\` is set, the commands will be ran in parallel; they'll by default be limited to a number of parallel tasks roughly equal to half your core number, but that can be overridden via \`-j,--jobs\`.- If \`-p,--parallel\` and \`-i,--interlaced\` are both set, Yarn will print the lines from the output as it receives them. If \`-i,--interlaced\` wasn't set, it would instead buffer the output from each process and print the resulting buffers only after their source processes have exited.- If \`-t,--topological\` is set, Yarn will only run the command after all workspaces that it depends on through the \`dependencies\` field have successfully finished executing. If \`--topological-dev\` is set, both the \`dependencies\` and \`devDependencies\` fields will be considered when figuring out the wait points.- If \`-A,--all\` is set, Yarn will run the command on all the workspaces of a project. By default yarn runs the command only on current and all its descendant workspaces.- If \`-R,--recursive\` is set, Yarn will find workspaces to run the command on by recursively evaluating \`dependencies\` and \`devDependencies\` fields, instead of looking at the \`workspaces\` fields.- The command may apply to only some workspaces through the use of \`--include\` which acts as a whitelist. The \`--exclude\` flag will do the opposite and will be a list of packages that mustn't execute the script. Both flags accept glob patterns (if valid Idents and supported by [micromatch](https://github.com/micromatch/micromatch)). Make sure to escape the patterns, to prevent your own shell from trying to expand them.Adding the \`-v,--verbose\` flag will cause Yarn to print more information; in particular the name of the workspace that generated the output will be printed at the front of each line.If the command is \`run\` and the script being run does not exist the child workspace will be skipped without error.`,examples: [[`Publish current and all descendant packages`,`yarn workspaces foreach npm publish --tolerate-republish`,], [`Run build script on current and all descendant packages`,`yarn workspaces foreach run build`,], [`Run build script on current and all descendant packages in parallel, building dependent packages first`,`yarn workspaces foreach -pt run build`,]],})
