This is a test file with some referenced equations, line
\begin{equation}{ this }\end{equation}
Some equations might be inside of text,
\begin{equation}{ for example }\end{equation} this one.
Some equations might be on start of paragraphs:
\begin{equation}{ start }\end{equation} of paragraph.
Other might be on separate paragraphs of their own:
\begin{equation}{ separate }\end{equation}
Some of those can be labelled:
This is a test file with some referenced equations, line
\begin{equation}\protect\hypertarget{eq:0}{}{ this }\label{eq:0}\end{equation}
Some equations might be inside of text,
\begin{equation}\protect\hypertarget{eq:1}{}{ for example }\label{eq:1}\end{equation}
this one.
Some equations might be on start of paragraphs:
\begin{equation}\protect\hypertarget{eq:2}{}{ start }\label{eq:2}\end{equation}
of paragraph.
Other might be on separate paragraphs of their own:
\begin{equation}\protect\hypertarget{eq:3}{}{ separate }\label{eq:3}\end{equation}
Then they can be referenced:
Individually eq.~\ref{eq:0}, eq.~\ref{eq:1}, eq.~\ref{eq:2},
eq.~\ref{eq:3}
Or in groups eqns.~\ref{eq:0}, \ref{eq:1}, \ref{eq:3}
Groups will be compacted
eqns.~\ref{eq:0}, \ref{eq:1}, \ref{eq:3}, \ref{eq:2}
