This small set of C routines is provided as a start up kit to users wanting to
link the HEALPix routines with some other languages (C, C++, IDL, perl, ...),
and it was actually mainly provided by various users (see individual routines
for details). As for the rest of the
HEALPix package, all interested persons are welcome to contribute to this effort.
