3.  Override directories
Need to modify the way we use SCons to make override directories possible.  Some of Joanne's existing GoGui code assumes that this ability exists.  The plan is to support one over-riding directory.  Leon states he can live with that.  That override directory may contain any number of packages.  The fix will come in the SConstruct files, which while not pretty, will be invisible to most users.

4. Not hold holding us up but annoying..
There are several places where version numbers are used.  The SConscript files have a version number.  When GoGui checks out a package, there is no longer a version subdirectory.

 Tom reports that there are three outstanding xrootd issues and one extra added by Tony:
https://jira.slac.stanford.edu/browse/GXR-46Image Removed
https://jira.slac.stanford.edu/browse/GXR-45Image Removed
https://jira.slac.stanford.edu/browse/GXR-44Image Removed
https://jira.slac.stanford.edu/browse/GXR-43Image Removed
He has been speaking to Andy, who suggests that he would prefer finding a way to more easily slide in newer versions of the xrootd client code into our ROOT library distributions.  At worst, we can always do what we did for v5.18.00c-gl1, where we obtained their updated xrootd client code and compiled it along with the rest of ROOT.

Chuck reports that his focus is on the iLat pages.  There have been concerns expressed about directing users to use specific versions of SciTools in conjuction with iLat.  Chuck suggests rolling out a tutorial that focuses on production versions of iLat and ScienceTools installed on SLAC public.  Heather would like to see the setup procedure for iLat be consistent for csh and bash.

The Data Access pages are also being updated.  The navigation bars have been laid out according to Tony's specifications.  However, at this time, iLat has taken priority.  Richard suggests that Chuck complete work on the standard point source analysis using iLat, then work on the data access pages, followed by creating the pages for extended sources.

How to update the workbook?  Chuck explained the working model used for the Science Tool pages.  The authors check pages out of CVS and check in the changes made using any HTML editor.  When they are complete, they notify Chuck who then incorporates them into the online version of the workbook.  The majority of the time spent by Chuck is making sure the format is consistent with the rest of the workbook.  Leon and Tom both asked how do we check out a specific page from the workbook?  Chuck offered to write up some directions.

There have issues with excessive memory use.  Tony will try out the new GR with updated RootIo with some additional JO parameters to see if that helps alleviate the problem.  Tony also suggests shutting off the rebuilding of ROOT indices when it is not necessary - this may also be a memory hog.

There are a variety of other issues:

1. Relations files
Never got relation file reading working yet.  Should review the HepRepSvc interface.

2.  MC vesus real data
Currently two versions of the jobOptions are required to handle MC versus real data jobs.  It would be better to handle this automatically.

3. Merit Display
Is it possible to provide Instance Trees similar to FRED?  This would be one way to display the contents of merit in Wired, as has now been added to FRED by Leon.

FRED

Outstanding issue with RHEL4 and Fox library.  Currently, one cannot run FRED on RHEL4 with our distributed version of FRED and Fox.  Joanne has pursued this issue in the past.  Heather and Joanne will discuss this further during the week and see if there is an easy solution such as upgrading the version of fox.
