I am getting started with the Yeoman workflow, but I can't seem to completely understand the "alternate search path" for the usemin task in the index.html file. For example, there are 2 blocks generated with the 'yo angular' command:
<!-- build:js scripts/modules.js -->
<script src="bower_components/angular-resource/angular-resource.js"></script>
<script src="bower_components/angular-cookies/angular-cookies.js"></script>
<script src="bower_components/angular-sanitize/angular-sanitize.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<!-- endbuild -->
vs.
<!-- build:js({.tmp,app}) scripts/scripts.js -->
<script src="scripts/app.js"></script>
<script src="scripts/controllers/main.js"></script>
<script src="scripts/directives/multiselect.js"></script>
<!-- endbuild -->
Why does the second one have the {.tmp, app} "alternate search path" (what does it mean)? Thanks in advance.
