From time-to-time I see questions from people asking about using Emacs for (prose) writing. There are many resources for that, some of which Irreal has explored. Screenwriters have special problems because their manuscripts have to adhere to strict formatting rules.
Happily, it turns out that Emacs can accommodate them too
Find of the month! #emacs screenwriter mode: https://t.co/GbwwolQWsn | managed to tinker it for a theatre script. Absolutely love it :-)
