Hi

I am using R for package writing in R, and the org file is under svn version
control.

I would like to keep the version of the R package, as stated in the
DESCRIPTION file, in sync with the svn revision, so I thought about using
variables for that.

But my approach below obviosly does not work, as in the tangled DESCRIPTION
file, it says Version: 0.$VER

Is it possible to have, during tangling, the actual value in the source file
instead of the variable?

Thanks,

Rainer
