Revision number into a file

Hello,
Am using svn for 2 years ago, implemented it in my job and we're working
with it.
I still have this problem :

Subversion is installed on a debian server from binaries, in each project,
we have a file called version, this file should include the last revision
number of the exported project, we're puting the revision number manually, i
would like to automate this task, so on each export, a hook will go and
replace a given string by the revision number.

Anyone can help ? thanks
