-% A new timeline package. Allows labeling of events with per day granularity. Other features include relative positioning with unit specification, adjustable tick mark step size, and scaling to specified width.
-% \end{abstract}
-%
-% \section{Introduction}
-% Most timeline packages and solutions for {\LaTeX} are used to convey a lot of information and are therefore designed vertically. If you are just attempting to assign labels to dates, a more traditional timeline might be more appropriate. That's what {\jobname} is for.
-%
-% \section{Usage}
-% \DescribeEnv{chronology}
-% Declare a |chronology| as follows:
-% \begin{alltt}\verb|\begin{chronology}|\oarg{step}\marg{startYear}\marg{endYear}\marg{unit}\marg{width}\\\meta{events}\\\verb|\end{chronology}|\end{alltt}
-% Where \marg{width} is the final width of the timeline. The width can be specified as a command (e.g.\ \cmd{\textwidth}). \marg{unit} specifies the distance between minor ticks. \oarg{step} (unitless) specifies how many units between major ticks, where the first starts $\equiv_{\bmod {\langle step\rangle}}0$. The timeline runs from \marg{startYear} to \marg{endYear}.
-% \DescribeMacro{\event}
-% Label an \cmd{\event} as follows:
-% \begin{alltt}\cmd{\event}\oarg{startDate}\marg{endDate}\marg{label}\end{alltt}
-% An \cmd{\event} with the label \marg{label} is created. If \oarg{startDate} is specified the \cmd{\event} should span to \marg{endDate}, otherwise the \cmd{\event} specifies a specific date. All dates are unitless.
-% \DescribeMacro{\decimaldate}
-% Specify a \cmd{\decimaldate} as follows:
-% \begin{alltt}\cmd{\decimaldate}\marg{day}\marg{month}\marg{year}\end{alltt}
-%
-% \StopEventually{\PrintChanges\PrintIndex}
