        Please note that it process only HDF-EOS files, and not
        arbitrary HDF's.

 NA> Could it be useful for GRASS?

        Yes.  However, please note that it's not free software (as
        defined by, e. g., DFSG [1]) nor open source (as defined by OSD
        [2].)

        My personal opinion is that it's a bit brain-damaged as well.
        Given that PROJ.4 [3] is free software, implementing a viable
        free software / open source alternative will probably take a
        developer-month or so (and I've some simple code which works for
        me on AIRS data, which aren't supported by HEG quite well.)
        (Although I'm not sure about the exact HDF-EOS libraries
        license.)

        Well, I've an Awk script or two to automagically convert
        `hegtool' output (.hdr) into a control file for swtif.

 NA> * I already read almost all mails in the list referering to the HDF
