Fixing file modes (Was: [boost] file modes in boost cvs)

I noticed that in boost cvs files seem to have random modes. Many sources show up as executable when checked out of cvs onto my Linux box. Hopefully this will be fixed before release.

Could our CVS experts comment on why this is happening/what would be the right way to fix it? TIA, -- Aleksey Gurtovoy MetaCommunications Engineering
