[ghns] Fwd: r397 - trunk/hotstuff/scripts

[Josef Spillner]

Hi there,

the pre-commit hook added below (and r398 which added the corresponding 
schema) can be used to verify *.meta files before they're added to SVN. The 
script isn't installed at data.kstuff.org yet but I could do that soon. An 
improvements would be to use xmlstarlet to get the preview/payload file paths 
and check if those files exist, although this requires more than svnlook 
since they might have been committed earlier already.

Josef
