<p>TUSTEP (Tubingen System of Text Processing Tools) is a free, open source, widely-used toolbox for text processing. It is aimed at scholarly audiences, can work with texts in both latin and non-latin scripts, and is primarily designed for humanites applications. Its modules include data capture, information retrieval, text collation, text analysis, sorting and ordering, rule-based textual manipulation, data export and typesetting. The user manual is only available in German at this time. This tool has been in continuous development since the 1960s.</p>
