Review of the Minutes from the Last Meeting

   We  went  over  the  [26]minutes  of  the meeting on November 4. David
   mentioned  that he did get a suggestion from Eugene Chudakov on how he
   might  approach  a  parametrization  of  a  three-dimensional magnetic
   field.

Next Action on Coding Rules

   David  reported  that he incorporated all suggestions made at the last
   meeting,  with  the  exception  of the suggestion to drop the "virtual
   destructor" rule. He could not generate a compiler error when the rule
   is violated, and so the rule has been retained.

   We  decided  to  vote  on  formal  adoption  of  the rules at the next
   meeting. David will write to the email list announcing this.

Warning-Free Code Policy

   Craig  proposed  that  we  make  it  a  policy that code build without
   warnings. There was some discussion:
     * David  noted  that  when  the  code  is  tried  on a new platform,
       warnings  may  arise.  Often  the  original  developer  will  have
       difficulty  getting  access to the new platform, a complication if
       warning-free  code  is the policy. We thought that if a good-faith
       effort   is  made  in  these  cases  the  collaboration  would  be
       satisfied.
     * There  may be cases where the warnings on some platforms require a
       substantial  amount of effort to fix while causing no real problem
       in code excecution. Mark thought that in those cases, an exception
       to  the  policy  could be made. This would have to be noted in the
       comments  inside  the  code.  This  addresses  the  concern in the
       previous bullet (to some extent).

   With these caveats in mind, we adopted the policy.

Action Item Review

   We went over the [30]list.
     * Mark  promised to present the new "Offline Computing" project plan
       at the next meeting.
     * Richard has promised to give us a presentation on the OSG soon.
     * There were several items that need to the crossed off the list.


New Action Items

    1. Note the no-warning policy in the coding conventions.
