htmlprocessor is a CLI‑tool (and the engine behind the **grunt‑processhtml** and **gulp‑processhtml** plugins) that scans HTML (or similar) files for special comment blocks and rewrites them—e.g., bundling CSS/JS references, conditionally stripping sections, or inserting data from JSON. It targets front‑end build pipelines and developers who need an easy way to automate HTML asset replacement and environment‑specific markup during Grunt, Gulp, or command‑line builds.
