+Scientific Data Format} - a proposed next generation interchange format for
+scientific data.  ASDF aims to exist in the same middle ground that made FITS
+so successful, by being a hybrid text and binary format: containing human
+editable metadata for interchange, and raw binary data that is fast to load
+and use.  Unlike FITS, the metadata is highly structured and is designed
+up-front for extensibility.")
