+This chapter provides the subcommand [[stats]], which outputs various 
+statistics.
+The [[stats]] command takes two subcommands:
+\begin{itemize}
+\item [[data]],
+\item [[grades]], and
+\item [[time]].
+\end{itemize}
+The [[data]] subcommand gives raw data points in CSV format that can be used to 
+analyze the data in some other (statistics) software.
+The [[grades]] and [[time]] subcommands output aggregated statistics.
+
+\section{The subcommand and its options}
+
+We add the subparser for [[stats]].
+<<add arguments>>=
+stats_parser = subp.add_parser("stats", help="Output stats of a course",
+    description="Output format: CSV")
+stats_parser.set_defaults(func=stats_command)
+<<set up options for selecting courses for stats>>
+@ Now, that [[users_command]] function must take two arguments: [[canvas]] and 
+[[args]].
+<<functions>>=
+def stats_command(canvas, args):
+  <<process options for selecting courses for stats>>
+@ We will cover the set up and processing of the options in the following 
+subsections.
+
+\subsection{Selecting the course}%
+\label{selecting-courses}
+
+We provide two ways to identify a course: by Canvas' ID number, which is 
+unique, or by matching the course name and course code against a regular 
+expression.
+We need a course, so we require one of these options, but not both.
+<<set up options for selecting courses for stats>>=
+course_args = stats_parser.add_mutually_exclusive_group(required=True)
+course_args.add_argument("-i", "--course-identifier", type=CourseID,
+  help="Select course by Canvas unique identifier")
+course_args.add_argument("-c", "--course-regex",
+  help="Filter courses by regular expression")
+@
+
+When we check for either of these arguments, we set up the [[course_list]] 
+object that will be used in [[<<get the list of stats>>]].
+<<process options for selecting courses for stats>>=
+if args.course_identifier:
+  course_list = [canvas.get_course(args.course_identifier)]
+elif args.course_regex:
+  course_list = filter_courses(canvas, args.course_regex)
+@ We use the [[filter_courses]] from \cref{filter-courses}.
+
+
+\subsection{Selecting the type of stats}
+
+We also want to be able to filter out the type of stats.
+For now, we focus on students and teachers.
+<<set up options for selecting type of stats>>=
+stats_parser.add_argument("-a", "--assignment", default=".*",
+  help="Choose assignment, default to all")
+@
+
+
+\section{Get and print the stats}
+
+We need the following data for a course:
+\begin{itemize}
+\item the start date ([[start_at]] attribute),
+\item the assignments ([[assignments]] attribute).
+\end{itemize}
+
+For each assignment, we need the following data:
+\begin{itemize}
+\item the due date ([[due_at]] attribute),
+\item the submissions ([[submissions]] attribute).
+\end{itemize}
+
+For each submission, we need the following data:
+\begin{itemize}
+\item the grade ([[grade]] attribute),
+\item the submission date ([[submitted_at]] or [[graded_at]] attributes).
+\end{itemize}
+
+We want the dates in [[datetime]] format, this way we can compute the 
+\enquote{day of the course} by just subtracting them.
+<<get stats and print them>>=
+<<collect the statistics>>

+stats_writer = csv.writer(sys.stdout, dialect="unix", delimiter="\t")
