+rollup version <%= version %>
+=====================================
+
+Usage: rollup [options] <entry file>
+
+Basic options:
+
+-v, --version            Show version number
+-h, --help               Show this help message
+-i, --input              Input (alternative to <entry file>)
+-o, --output <output>    Output (if absent, prints to stdout)
+-f, --format [umd]       Type of output (amd, cjs, es6, iife, umd)
+-n, --name               Name for UMD export
+-u, --id                 ID for AMD module (default is anonymous)
+-m, --sourcemap          Generate sourcemap (`-m inline` for inline map)
+
+
+Example:
+
+rollup --format=cjs --output=bundle.js -- src/main.js
+
+
+Notes:
+
+* When piping to stdout, only inline sourcemaps are permitted
