renames a pdf file to author-title-year.pdf or other formats based on your selection. there isn't actually anything scholarly about this tool, though academic people may find it useful for renaming pdfs that come in arbitrarily named file formats. services like mendeley kind of make this not super relevant. it helps when searching for a specific pdf and when labeling pdfs.
