I would like to automate the creation of routine office correspondence - letters, etc. I am currently using Hotdocs for this task but would prefer to find something that isn't tied to Windows and something that could be more easily integrated into an automated workflow - e.g., could be used in a scripting environment.
I could roll my own with Perl/Python, and could probably adapt one of the HTML-oriented template systems to this task, but if someone's already done this, that'd be even better.
