All calls to html_requires//1
for the page are collected and duplicates are removed. Next, the
following steps are taken:
- Add all dependencies to the set
- Replace multiple members by‘aggregate’scripts or css
files. see use_agregates/4.
- Order all resources by demanding that their dependencies preceede
the resource itself. Note that the ordering of resources in the
dependency list is ignored. This implies that if the order
matters the dependency list must be split and only the primary
dependency must be added.
