You could have downloaded PSTextMerge 4.1 for Mac from our software library for free. This Mac app is an intellectual property of Herb Bowie. The application is included in Developer Tools.
From the developer:
PSTextMerge (was TDF Czar) merges lists of data into text templates to create fully populated text files. The output files can be Web pages, XML files, RSS Feeds or any other varieties of text files. The input data can be obtained from a tab-delimited data file, or directly from a Microsoft Excel spreadsheet. You can record and easily play back recorded scripts, making it easy to re-generate your output text files when your data changes.
You may want to check out more software for Mac, such as JBuddy Bot Builder, HexDecBin or Pleinpot, which might be related to PSTextMerge.
