I try to get the abstract heading set to the left and the package abstract seems to provide this functionality. But the pdf contains the characters "centerflushleft" and the abstract title is centered. Is the package broken? I use texlive 2012. Is there another way to achieve the desired result?
\documentclass{scrartcl}
\usepackage{abstract}
\begin{document}
\absnamepos{flushleft}
%\abstitlestyle{\abstractname}
\setlength{\absleftindent}{0pt}
\setlength{\absrightindent}{0pt}
\begin{abstract}
\noindent
This paper provides an overview of the most important grammatical properties of German. A large part
of the paper is concerend with the basic clause types of German. I start with the Topological Fields Model,
which is very useful as a descriptive tool, but -- as will be shown -- not sufficient for a thorough
account of German clausal structure. I therefore explain additional theoretical assumptions that
were made in order to assign structure to the observable linear sequences. After a sketch of an
analysis of the basic sentence patterns, I
give an account of passive, case assignment, and subject-verb agreement.
