This is one of the oddest requests. I did not like the designs of parseltoungue and obit in that they did not take advantage of the AIPS program itself and otherwise were in some way dependent on particular versions of AIPS. Nonetheless I explored the AIPS
rsync area and discovered the library you requested. I have moved a copy to my ftp area
