Developer file created by BBEdit, a Mac OS X source code editor; contains rules for automatic processing of text; may contain text replacements, sorting instructions, or other manipulations; used for saving and reusing text factory settings.

Text factory files allow developers to perform batch updates of source code files. For example, a developer could use a TEXTFACTORY file to change all header information in project files. BBEdit can run text factories in the background so that development can continue while the program performs the updates. NOTE: TEXTFACTORY files are also used by Bare Bones Software's Text Wrangler editor.
