Eric Winter handling tip modifications.  Heather to handle cfitsio upgrade, which should just require picking up the new cfitsio we already have available.

Sounds like we might be ready?

We have been stuck with an old version of cfitsio because some code, specifically some code in pulsar tools, requires an undocumented feature of that version which is explicitly not supported in newer versions, namely simultaneous access by more than one client of memory-resident files. Attempts to add this support to tip itself have so far been unsuccessful. It's clear that, at the very least, it would involve a substantial reworking of the package, so Eric took a different tack: he modified the pulsar code to use a disk file. This 2-line change appears to have done the trick. He has so far tested with SL5, 32- and 64-bit, and snow leopard.

Sweep through online workbook to determine updates/modifications needed. - moderate priority.
