\HeaderA{promptPackage}{Generate a Shell for Documentation of a Package}{promptPackage}
\keyword{documentation}{promptPackage}
\begin{Description}\relax
Generates a shell of documentation for an installed or source package.
\end{Description}
\begin{Usage}
\begin{verbatim}
promptPackage(package, lib.loc = NULL, filename = NULL,
              name = NULL, final = FALSE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{package}] the name of an \emph{installed} or \emph{source} package
to be documented.
\item[\code{lib.loc}] a character vector describing the location of \R{}
library trees to search through, or \code{NULL}.  The default value
of \code{NULL} corresponds to all libraries currently known.  For a
source package this should specify the parent directory of the
package's sources.
\item[\code{filename}] usually, a connection or a character string giving the
name of the file to which the documentation shell should be written.
The default corresponds to a file whose name is \code{name} followed
by \code{".Rd"}.  Can also be \code{NA} (see below).
\item[\code{name}] a character string specifying the name of the help topic,
typically of the form \code{<pkg>-package}.
\item[\code{final}] a logical value indicating whether to attempt to
create a usable version of the help topic, rather than just a shell.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
Unless \code{filename} is \code{NA}, a documentation shell for
\code{package} is written to the file specified by \code{filename}, and
a message about this is given.  

If \code{filename} is \code{NA}, a list-style representation of the
documentation shell is created and returned.  Writing the shell to a
file amounts to \code{cat(unlist(x), file = filename, sep = "\bsl{}n")},
where \code{x} is the list-style representation.

If \code{final} is \code{TRUE}, the generated documentation will not
include the place-holder slots for manual editing, it will be usable
as-is.  In most cases a manually edited file is preferable (but
\code{final = TRUE} is certainly less work).
\end{Details}
\begin{Value}
If \code{filename} is \code{NA}, a list-style representation of the
documentation shell.  Otherwise, the name of the file written to is
returned invisibly.
