I have hundreds of product manuals that all have a generic warning (A) at the beginning that has been imported into all of the manuals (B). Then when A gets updated, I would like to have a script that opens all of the .fm files (B) in a directory and publishes updated PDFs with the updated content from A.
I am not familiar with Framemaker, but do have experience with Photoshop Actions for performing batch edits.
Please see the FM EULA. IMHO it's not allowed to do such Automation by the EULA. You need FM Publishing Server license to do this. And than there's no need for Scripting, as you can publish in a nightly build if Textinsets update automatically.
