Command line tool to manipulate ASDF scientific data files
ASDF (Advanced Scientific Data Format) is 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. . This package contains the asdf command line tool.
