The syntax is simple: just add an  underline at the end, when referencing
it, like [1]_. The definitions should start with "..", like ".. [1] something".

Sphinx will automatically generate the reverse reference(s) at the html output.

Yet, sometimes (like the above), it needs to be escaped by a "\ ", as ReST would
recognize "foo[1]_" as something else.

Ps.: it also accepts an "auto-numbered" references like [#]_, but such syntax
require some care, in order to avoid wrong cross-references.
