Determine correct library overview for non-standard modules #253
Description
Certain non-standard modules such as api-common-java, gax, and java-common-protos don't follow the standard installation instructions of using a bom. We should determine what the library overview page for these modules should look like (potentially just copying the README.md file, similar to how we copy the CHANGELOG.md file).
Depending on the outcome, we may not need to make any doclet changes and the changes could be entirely within the g3 script.
