New Formula: fits

The File Information Tool Set (FITS) identifies, validates, and extracts
technical metadata for various file formats. It wraps several third-party open
source tools, normalizes and consolidates their output, and reports any
errors. FITS was created by the Harvard University Library Office for
Information Systems for use in its Digital Repository Service (DRS).
