The script uses one extra file, header.inc, which contains customizations:
\documentclass[a4paper,11pt,oneside]{article}
\usepackage{a4wide} % Iets meer tekst op een bladzijde
\usepackage[dutch]{babel} % Voor nederlandstalige hyphenatie (woordsplitsing) en het euro-symbool
\usepackage{amsmath} % Uitgebreide wiskundige mogelijkheden
\usepackage{amssymb} % Voor speciale symbolen zoals de verzameling Z, R...
\usepackage{url} % Om url's te verwerken
\usepackage{graphicx} % Om figuren te kunnen verwerken
\usepackage[small,bf,hang]{caption} % Om de captions wat te verbeteren
\usepackage{xspace} % Magische spaties na een commando
\usepackage[utf8]{inputenc} % Om niet ascii karakters rechtstreeks te kunnen typen
\usepackage{float} % Om nieuwe float environments aan te maken. Ook optie H!
\usepackage{flafter} % Opdat floats niet zouden voorsteken
\usepackage{listings} % Voor het weergeven van letterlijke text en codelistings
\usepackage{marvosym} % Om het euro symbool te krijgen
\usepackage{eurosym} % Om het euro symbool te krijgen
\usepackage{textcomp} % Voor onder andere graden celsius
\usepackage{fancyhdr} % Voor fancy headers en footers.
\usepackage{graphics} % Om figuren te verwerken.
\usepackage[a4paper,plainpages=false]{hyperref} % Om hyperlinks te hebben in het pdfdocument.
\usepackage[usenames,dvipsnames]{xcolor}
% Definitie algemene macro's
\newcommand{\npar}{\par \vspace{0.2ex }}
\setlength\textheight{9.75in}
\setlength\textwidth{7in}
\topmargin -0.5in
\headheight 0.0in
\oddsidemargin -.25in
[Update] You can also try the following method, using abiword, but the method above yields better results, in my opinion:
abiword --to=tex "filename.pdf"
