Three years ago Aaron Reed, Graham Nelson, David Kinder and myself hashed out a system for automatically generating personal copies of Parchment in Inform 7. By simply adding a single line to your code you would be given a website which you could upload to your website or stick on a USB drive, removing the need to tell someone to install an interpreter first. This is pretty common now, and all the major IF development systems now support some kind of web play, but at the time it was big progress.
For a while though Parchment for Inform lagged behind the standard version of Parchment because I needed to manually update it. Most of the time it was straight forward, but sometimes the changes in Parchment would need a little massaging to work for Inform. There was a sad time when the Inform version of Parchment wasn't updated for over a year.
But now, thanks to Grunt, the Inform package is built automatically. Whenever I update Parchment, the Inform package is updated too. Most people just use the version of Parchment included within Inform itself, but if you're the kind of person who loves to have the newest everything, you can now be assured that the current Parchment for Inform package is truly up to date!
