| Barback is an asset build system. It is the library underlying | |
| [pub](http://pub.dartlang.org/doc/)'s asset transformers in `pub build` and | |
| `pub serve`. | |
| Given a set of input files and a set of transformations (think compilers, | |
| preprocessors and the like), it will automatically apply the appropriate | |
| transforms and generate output files. When inputs are modified, it automatically | |
| runs the transforms that are affected. | |
