Renaming a KiCad project

I keep my projects in svn, and kicad made it more challenging than I expected to rename a project. The orignal project was igbt-tx, and my new project is tx-3x1. First, you rename the top level project:

for f in igbt-tx*; do svn mv "$f" "$(echo $f | sed 's/^igbt-tx/tx-3x1/g')"; done

You then need update the libraries:

find ./ -type f -exec sed -i 's/igbt-tx/tx-3x1/g' {} \;

If you want to do this without svn, you need to just remove the "svn".
