layouts: add custom layout for those of us that need weird mappings This adds a config-driven custom layout, targeted at the case where you need to fetch a small subset of a large number of subversion branches, or where your subversion layout doesn't match the standard trunk/branches/tags layout very well.

#!/bin/sh
. $(dirname $0)/common.sh

for b in `hg branches -aq` ; do
    hg co $b || break
    echo verifying $b
    hg svn verify
done
