| Question: How do I use one trove I have built when building another one? | ||
Answer: To use one trove when building another, specify both troves in the same job. rMake will build them in the correct order and use the newly built version of one trove when building the other. Currently, there is no way to use a trove from an earlier job to rebuild a trove in a later job.
