This script reverses the actions of TaskPaper's standard menu item "Archive Done Tasks". Specifically, in the front document, it moves each task in the "Archive" project that does not have a @done tag, back to the project specified by the value of the @project tag. If the original project does not exists, a new project with that name is created at the beginning of the document. The project tag is stripped from the task. If the task does not have a @project tag, the task is moved to the beginning of the document. WARNING: This will not work properly if there are parentheses in the name of a project.
