[Bioc-devel] executable vignette?

[cstrato]

Dear all

Can you tell me when is a vignette for a package, e.g. "mypkg", an 
executable file?
How can I avoid that my vignette is an executable file?
Is there something special that I have to add to my vignette?

In "mypkg" the vignette  with example name "mypkg.Snw" is located in 
subdirectory
"inst/doc" as suspected, and it looks as follows:

%\VignetteIndexEntry{MyPkg Vignette: Overview}
%\VignetteDepends{mypkg}
%\VignetteKeywords{Expression}
%\VignettePackage{mypkg}
\documentclass{article}

\usepackage{hyperref}

\textwidth=6.2in
\textheight=8.5in
%\parskip=.3cm
\oddsidemargin=.1in
\evensidemargin=.1in
\headheight=-.3in

\newcommand{\Rfunction}[1]{{\texttt{#1}}}
\newcommand{\Rmethod}[1]{{\texttt{#1}}}
\newcommand{\Rcode}[1]{{\texttt{#1}}}
\newcommand{\Robject}[1]{{\texttt{#1}}}
\newcommand{\Rpackage}[1]{{\textsf{#1}}}
\newcommand{\Rclass}[1]{{\textit{#1}}}
\newcommand{\mypkg}{\Rpackage{mypkg}}
