    1484 <Text id="assoc-files-9">Note 1: as this is an option that is categorized under the <Autotext text="BasePlugin"/> heading, it is therefore an option that is available across all the plugins provided by Greenstone. In our example, we happen to be binding a PDF document to a Word document, however it could equally be used to bind MP3 versions of files to PNG artwork of album covers.</Text>
    1485 <Text id="assoc-files-10">Note 2: More than one filename extension can be provided as part of this option, separated by a comma. For example, setting the value of the associate_ext in <Autotext text="TextPlugin"/> to <Autotext text="avi,png" type="italics"/> would allow both an AVI video file (say an oral history interview) and a PNG image (say a picture of the interviewee taken at the time of the recording) to bind to a text version of the document (say representing a transcript of the interview). Both AVI and PNG versions of the file can be present at the same time, or alternatively only one of the two file types need be present, or neither, and Greenstone will process the situation accordingly.</Text>

    14861486<Text id="assoc-files-11">Note 3: The option <Format>associate_ext</Format> is in fact a simplified version of a more general option <Format>associate_tail_re</Format>. Using regular expression syntax, the latter provides a more powerful way of manipulating filenames. Rather than focus on just the filename extension, with <Format>associate_tail_re</Format>, one is able to group files together that share a similar filename root, but might start to differ in characters before the filename extension. For instance, the Word version of the document might be <Format>my-article.doc</Format> but the PDF version might be <Format>my-article-ver13.pdf</Format> reflecting the fact that the PDF file is saved in version 1.3 of this format. Using <Format>associate_tail_re</Format> (and a little bit of regular expression know-how!), such differences can be surmounted, and the two files still processed automatically as different versions of the same document.</Text>
