%description
Utilities to read and write files in the FITS (Flexible Image Transport
System) format, a standard format in astronomy (see e.g.
<https://en.wikipedia.org/wiki/FITS> for more information). Present
low-level routines allow: reading, parsing, and modifying FITS headers;
reading FITS images (multi-dimensional arrays); reading FITS binary and
ASCII tables; and writing FITS images (multi-dimensional arrays).
Higher-level functions allow: reading files composed of one or more
headers and a single (perhaps multidimensional) image or single table;
reading tables into data frames; generating vectors for image array axes;
scaling and writing images as 16-bit integers.  Known incompletenesses are
reading random group extensions, as well as complex and array descriptor
data types in binary tables.
