Revision 1.5 - (show annotations) (download)
Fri Sep 10 12:19:31 2004 UTC (19 years, 8 months ago) by edhill
Branch: MAIN
CVS Tags: checkpoint55, checkpoint54f_post, checkpoint55c_post, checkpoint55b_post, checkpoint55a_post
Changes since 1.4: +6 -8 lines 
 o overhaul of IO so that we now have flags for MDSIO and/or MNC
   - all verification tests compile and run with linux_ia32_g77
   - defaults are compatible with current input files--nothing
     should change if you were not previously using MNC
   - MNC output has been added in numerous places (eg. timeave)
     but there are still a few writes not yet do-able with MNC
     (this is in progress)
   - flags now allow for either/or/both use of MDSIO and MNC and
     documentation will soon follow
   - numerous small formatting cleanups for ProTeX
