grunt-dtsm is a Grunt plugin that integrates **DTSM** (the TypeScript definition manager) into a project's build workflow. It lets developers run DTSM commands—such as installing and updating `.d.ts` definition files—directly from their Gruntfile by specifying a `dtsm.json` configuration. The tool is aimed at front‑end developers who use Grunt to automate tasks and need to manage TypeScript type definitions as part of their build process.
