... Reported here are recent efforts to explore minimal buy-in software through the implementation of Funtools, a small suite of FITS library routines and analysis programs that attempts to hide the complexity of FITS coding. In particular, the use of "natural order" in the Funtools design enables it to "do the right thing" automatically. ... In addition, if the output file has inherited the input handle, then the output file also will know about columns having "w" mode. ...
