By having an index for the pages, it'd allow clients
to build autocomplete's and show an index of pages
making only one request (think `tldr list`). Subsequent
caching of this file would prevent further requests.
Included is a makefile to easily rebuild the index.
It could be tailored in case the pages structure changed.
In a particular case, the web client would benefit greatly
from an index. It'd know exactly what folder a command is in
and thus the number of requests would drop from 4 to 1.
