Fountain_(markup_language)
Fountain is a free and open-source plain text markup language that makes it possible to write a formatted screenplay in any text editor, on any device, using any software that edits text files.[1]
Fountain (which got its name from Fountain Avenue, the famous Hollywood shortcut[2]) was inspired by John Gruber’s Markdown, and has its origins in two different and non-related projects: Scrippets, developed by John August and Nima Yousefi, and Screenplay Markdown, developed by Stu Maschwitz.
