+This package helps you write source code in your articles
+and make sure it looks nice. Install it from CTAN and then
+use like this (pay attention to the \ff{\char`\\ff} command
+and the \ff{ffcode} environment):
+
+\begin{multicols}{2}
+\setlength{\parskip}{0pt}
+\scriptsize
+\raggedcolumns
+\begin{verbatim}\documentclass{article}
+\usepackage{ffcode}

+The function \ff{fibo()} is recursive:
+\begin{ffcode}
+void fibo(int n) {
+ if (n < 2) {
+ return n; |$\label{ln:ret}$|
+ }
+ return fibo(n - 1) + fibo(n - 2);
+}
+\end{ffcode}
+The line~\ref{ln:ret} terminates it.
+\end{document}
+\end{verbatim}

+The function \ff{fibo()} is recursive:
+
+\begin{ffcode}
+void fibo(int n) {
+ if (n < 2) { |$\label{ln:ret}$|
+ return n;

+ return fibo(n - 1) + fibo(n - 2);
+}
+\end{ffcode}
+
+The line~\ref{ln:ret} terminates it.
+\end{multicols}
+
+You have to run \ff{pdflatex} with the \ff{--shell-escape} flag
+in order to let \ff{minted} (the package we use) to run Pygments
+and format the code. If you don't want this to happen,
+just use the \ff{nopygments} option.
+
+More details about this package you can find
+in the \ff{yegor256/ffcode} GitHub repository.
