| 4 | -- where the definition of 'interesting' changes but is roughly: |
| 5 | -- "Interesting for bounding box hierarchy benchmarks." |
| 6 | -- |
| 7 | -- Currently, the approach is to output, in equal ammounts, the names of the files that |
| 8 | -- have most commands, and the names of the files that use the least popular commands. |
