I have downloaded now again the sources via "svn co
http://svn.gnucash.org/repo/gnucash/trunk/packaging/win32/ gnucash".
But I still cannot find anything like "autogen" in the downloaded
files. You see, I am real greenhorn. Did I use a wrong svn command? Or
should I just try to build from these source again?
