Boa Program: converted-uses.boa
Raw Data: converted-uses.txt
Figure 16 Generator: converteduses.java

This material mines potential conversions, shown in Figure 16.

Data: conversions

This is the material used to manually verify the data shown in Figure 16. If a potential conversion was verified, it is replaced with a URL to the revision on SourceForge. If it wasn't verified, it was prefixed with '--' (meaning not a conversion) or '??' (meaning a complex conversion, that also included many other code changes). A few are marked '!!' meaning we had problems finding the revision online.
