Dave pointed out some nice features such as embedding latex style equations
in the comments and automatically generated call graphs.

The new DQuickFit class was also shown. This makes use of the new MCCheatHits
factory which produces a single list of XYZ points with track numbers
(and detector system id) from cheat codes buried in the GEANT data. The
list includes hits from CDC, FDC, BCAL, TOF, CHERENKOV, and FCAL.

Some pictures were shown with track results from the DQuickFit using
the hdview program:

3. Ed gave a brief overview of the pacman utility.

Pacman helps create and maintain software distributions. It uses HTTP
as the transport mechanism with wget as the agent. The will allow us to
specify both internally developed and external binary and source packages
which have dependancies on one another. Something like a cross-platform,
network savvy RPM.

Ed has been in contact with the primary author who has expressed a 
willingness to help with any problems we run into. Ed will create some
test packages to gain more familiarity with the system.
