I've integrated dirtree package into a LaTeX document I am working on, but it appears to be interfering with the document format (see image here 1). How do I tell LaTeX to maintain original formatting after dirtree?
\documentclass{article}
\usepackage{dirtree}
\usepackage[parfill]{parskip}
\begin{document}
This is just a test.
\begin{itemize}
\item This is a test 1
\item This is a test 2
\item This is a test 3
\end{itemize}
\dirtree{%
.1 \framebox{\textbf{NDLTD}}.
.2 GATECH.
.2 \framebox{\textbf{OCLC}}.
.3 OCLCNo--477262203.metadata.
}
\begin{itemize}
\item This is a test 1
\item This is a test 2
\item This is a test 3
\end{itemize}
\end{document}

Update #1
I just discovered, while preparing a minimum working example, that the problem is as a result of loading the parskip package.

\documentclass{...}and ending with\end{document}. In my machine, I don't get a crammed output as you did. – hpesoj626 Dec 23 '12 at 09:15parskippackage withparfilloption. – lightonphiri Dec 23 '12 at 10:220.2try enclosing\dirtree{}with braces. – hpesoj626 Dec 23 '12 at 10:56
