Alan Jonchkeere presented the latest state of the Code Management Working group.
The group produced a draft document and they are now in the process of changing
it after having seen the BaBar & Moose Code Management systems. 

Look to the Web pages in the Software Tools area under Code Management for a
detailed description of what they are doing.

They have now decided to attempt to use the BaBar CMS system. Alan will be
attempting to install it and see what needs to be done to make it work for us.

We still need to think about how bug fixes and the current production scheme fit
into the CMS structure since when you checkout code from the system you check
out a whole package.

Serban then presented the latest Library Structure suggestion. He first showed a
list of the current D0 library structure organized by type of "package". The big
question of course is how do we define a package. A discussion of package
definitions followed. It was decided that a smaller group should come up with a
definition for a package.

Harrison then asked whether or not we could redefine a package definition and if
the CMS system could be changed to reflect that definition. Alan said that it is
"hard" to move code from one package to another but you can create a new
package, put the code in it and delete the old package. Fritz asked whether or
not the history would be lost. Alan responded that you delete the stuff by
storing it in the CMS "attic".

A discussion then followed again about package definition. Alan said that a
package is what one person works on. John H. said this implies that we want
packages to be small. He asked whether or not we could use branch and merge
feature of CMS as well. Alan said that the system prior (SDSS CVS) to the latest
one (BaBar CMS) would have allowed single file checkout. The current one does
not.

A discussion about code compilation occurred. It was suggested that a tool exist
for the CMS system that would tell a user if they change a header file, what
other files they may have affected. John H. also suggested that their should be
a tool that makes a makefile for you when you are making code changes and wish
to test code.

Laura then presented a status of the database group. A detailed description of
the recommendations that the database group will make will be ready by the
collaboration meeting. The Objectivity Database was originally removed from
consideration but people felt it should be added back in so it will be in the
recommendation.

Lee was then to present the GUI groups latest work. Time ran out however so
again look to the Software Tools Web page for the GUI groups latest and
greatest.
