// This is an helper script to generate the resources used by eDEX to display file-specific icons in fsDisp, from a fresh file-icons/source GitHub clone.
// Generated files are:
// - src/assets/icons/file-icons.json: monolithic JSON files containing SVG data needed to draw all the icons.
// - src/assets/misc/file-icons-match.js: script to match filenames to icons by using regex expressions.
//
// The generated files are pretty-printed. See prebuild-minify.js for automatic, on-CI minification of source files before bundling them in binary release assets.

// BEFORE RUNNING THIS SCRIPT:
// - npm run init-file-icons
// You can then use `npm run update-file-icons` which will pull the git submodules and run this script.
