[NTG-context] RME and INI

Hi all! TEXEXEC documentation and self documented 'texexec.rme' file says that it should be copied to 'texexec.ini'. First of all; I have two 'texexec.rme' in TeX tree; first in ...TeX/context/config the second in ...TeX/context/perltk Files looks to be identical but and the second location has a priority. But which location is more convenient for texexec config file? The second question is WHY I have to copy 'texexec.rme' to 'texexec.ini'? If I do so and change some settings in 'texexec.ini' and than run 'texexec --verbose', I can see that settings are still taken from 'texexec.rme'. Could You tell me what is the point in copying RME to INI and when INI file is used instead RME? Thanks, Pawe/l
