SubWCRev should write file ony when it's modified

Hi,

we use subwcrev utility to process a template and write a file that contains
information about the current subversion revision. This is done in a
pre-build event in Visual Studio 2010 and works fine so far, but causes that
the project will completely be recompiled every time. The subwcrev tool
processes the template and writes a new result file, which has a new
timestamp. The compiler now sees modified files and rebuilds the assembly -
every time.

My idea is to make subwcrev to read an probably existing target file before
a new one is written and simply compare it to the new data. If nothing
changed, the file should be left untouched. Is this possible?

Carsten
