\section{Introduction}
This package provides script named \package{ctanbib} which can be used for retrieving of the bibliographic information for packages hosted on CTAN.
\section{Usage}
It can be used in the following way:
\noindent\package{ctanbib [options] $\langle$packagename$\rangle$ > filename.bib}
\section{Available options}
\begin{description}
\item[-c,-\/-ctan] use the \texttt{@ctan} type instead of \texttt{@manual}.
The difference between the two is that the url field contains packages CTAN
path, instead of a link to the package.
\item[-h,-\/-help] print the help message.
\item[-v,-\/-version] print the version info.
\end{description}
\section{Examples}
\begin{verbatim}
ctanbib latex
\end{verbatim}
\noindent This invocation will print data in the Bib\LaTeX\ format to the standard output:
\begin{verbatim}
@manual{latex,
title = {The Latex package},
subtitle = {A TeX macro package that defines LaTeX},
author = {Lamport, Leslie and The LaTeX Team},
url = {http://www.latex-project.org/},
urldate = {2018-08-23},
date = {2018-04-01},
version = {PL 5}
}
\end{verbatim}
The \texttt{--ctan} option:
\begin{verbatim}
ctanbib -c hyperref
\end{verbatim}
\noindent This produces a bib record with the \texttt{@ctan} type:
\begin{verbatim}
@ctan{hyperref,
title = {The Hyperref package},
subtitle = {Extensive support for hypertext in LaTeX},
author = {Rahtz, Sebastian and Oberdiek, Heiko},
url = {/macros/latex/contrib/hyperref},
urldate = {2018-08-27},
date = {},
version = {6.86b}
}
\end{verbatim}
