[NTG-context] Update ConTeXt 2004-12-06 for teTeX 2.99.4-beta: map files

Hi all, I have a running tetex-2.99.4-beta. Now I would like to update ConTeXt to version 2004-12-06. After comparing directory structures I see there is difference: 1. In ConTeXt all map files are in fonts/map/pdftex/context/*.map 2. In teTeX amm map files are in fonts/map/dvips/context/*.map So my question is how I could update ConTeXt safely ? Which directory structure I have to follow ? teTeX will continue to work if map files installed in ConTeXt's structure ? Thank you in advance, Regards, Quy NGUYEN-DAI
