[Dev-luatex] svn revision ids

Hi, As of revision 3436, luatex once again reports a svn revision id in the banner when it has been built on a system with a working 'svn' command. The script that fetches the number is based on an idea of Reinhard Kotucha, and uses 'svn info URL' to get the number. The script is source/texk/web2c/luatexdir/getluatexsvnrevision.sh, and it is currently run from build.sh and from the tools/luatextag script. The latter is used to create the source tarballs. I am curious how it works out for other people, as it is quite possible that I made a thinking error yet again. Best wishes, Taco
