# Minor Updates

1. Edit ./fetchsrcs.sh to point to the updated URL.
2. Run ./fetchsrcs.sh.
3. Build and enjoy.

# Major Updates

1. Make a copy of this directory. (We like to keep the old version around
   for a short time after major updates.)
2. Delete the tmp/ subdirectory of the copy.
3. Follow the minor update instructions above.
4. Package any new Qt modules, if necessary.
