getting revision number into text file inside the working copy folder

Dear subversion users,

I am trying to automatically get the actual revision number of my subversion repository into a text file inside the subversion project.

More precisely, I am using subversion to keep track of the changes I do to the code of several R packages. These packages contain a file named "DESCRIPTION" containig (amongst other) the following line:

Version: 0.5.0.1

When I "build" these packages into *tar.gz R packages (by running R CMD build ... ) this version number is automatically used as the number for that R package and can be accessed easily from within R by running sessionInfo() after loading this package.

Now I would like to have the last digit (1 in this case) to resemble my subversion revision number to get a direct reference from within R to the version of the code that was used to compile the package.

I did the following:

1. run the following in the folder where DESCRIPTION is:

svn propset svn:keywords "LastChangedRevision" DESCRIPTION

2. And changed the relevant line in DESCRIPTION to:

Version: 0.5.0.$LastChangedRevision$

This works partially but changes the line in DESCRIPTION to (for example):

Version: 0.5.0.$LastChangedRevision: 28 $

I need, however:

Version: 0.5.0.28

Is there any way to achieve this? In case you have any solution, try to post it understandable to a SVN-newbi :-).

Thanks for your help!
Jannis
