This is a test file with some referenced equations, line \[ this \]
Some equations might be inside of text, \[ for example \] this one.
Some equations might be on start of paragraphs:
\[ start \] of paragraph.
Other might be on separate paragraphs of their own:
\[ separate \]
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}
