0.4: 9 August 2013
------------------
* Add hsenv compatibility.
* Big improvements in the way rebuilding is handled:
- Strip comments before deciding whether to rebuild, so
changing only comments does not trigger a rebuild
- Take local imports into account: if a diagram has an import
which corresponds to a local file, rebuild if that file has
changed
- Rebuild when options (e.g. size) change
