hi.
How can i exec external command within Jamfile to fill SVN_REVISION
define?

#this is Jamfile
#command is 'svnversion -n .'
project tests : requirements <include>.. <define>SVN_REVISION=1 ;

lib jpeg : : <name>jpeg ;
lib tiff : : <name>tiff ;

exe tests	: [ glob *.cpp ] ../loki//loki/<link>static
../src//images/<link>static jpeg tiff : <include>../src ;

Or maybe i can run shell script from Jamfile to form some header with
current revision version (as this project will only compiled under
UNIXes).
