Virtual machine designed to run various dynamic programming languages

Inform is a programming language and design system for interactive fiction originally created in 1993 by Graham Nelson. Inform can generate programs designed for the Z-code or Glulx virtual machines. Versions 1 through 5 were released between 1993 and 1996. Around 1996, Nelson rewrote Inform from first principles to create version 6 (or Inform 6). Over the following decade, version 6 became reasonably stable and a popular language for writing interactive fiction. In 2006, Nelson released Inform 7 (briefly known as Natural Inform), a completely new language based on principles of natural langua

ExifTool is a free and open source software program for reading, writing, and manipulating image, audio, video, and PDF metadata. As such, ExifTool classes as a tag editor. ExifTool can also be used as a metadata removal tool for supported file types, except for PDF, as old metadata is never actually deleted. (However, after running ExifTool the old metadata may be removed permanently using the "qpdf" utility) It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application.
