+# Generic Makefile for building and packaging a Nextcloud app which uses npm and
+# Composer.
+#
+# Dependencies:
+# * make
+# * which
+# * curl: used if phpunit and composer are not installed to fetch them from the web
+# * tar: for building the archive
+# * npm: for building and testing everything JS
+#
+# If no composer.json is in the app root directory, the Composer step
+# will be skipped. The same goes for the package.json which can be located in
+# the app root or the js/ directory.
+#
+# The npm command by launches the npm build script:
+#
+#    npm run build
+#
+# The npm test command launches the npm test script:
+#
+#    npm run test
+#
+# The idea behind this is to be completely testing and build tool agnostic. All
+# build tools and additional package managers should be installed locally in
+# your project, since this won't pollute people's global namespace.
+#
+# The following npm scripts in your package.json install and update the bower
+# and npm dependencies and use gulp as build system (notice how everything is
+# run from the node_modules folder):
+#
+#    "scripts": {
+#        "test": "node node_modules/gulp-cli/bin/gulp.js karma",
+#        "prebuild": "npm install && node_modules/bower/bin/bower install && node_modules/bower/bin/bower update",
+#        "build": "node node_modules/gulp-cli/bin/gulp.js"
+#    },
