handlebars-fileset is a Handlebars helper that allows users to create and manipulate filesets within their Handlebars templates, providing access to the file-set library's functionality. It's designed for developers using Handlebars who need to dynamically generate and process file lists based on patterns, making it particularly useful for static site generators, documentation tools, or any Node.js project that uses Handlebars for templating and needs file system operations.
