{This package is implemented by new primitives of encTeX of Feb 2003^^J
but this extension was not detected in your system. You can continue^^J
but all commands of `encxvlna' will be ignored. If your TeX distribution^^J
contains encTeX but does not activate it, you have to create the format^^J
using the -enc switch (e.g. in fmtutils.cnf). If you do not have encTeX^^J
at all, you have to compile it from the source code. You can find^^J
the source code including documentation at^^J
