devel/tagref 1.10.0_9 DragonFly

tagref helps to maintain code references in codebases.

Tagref ensures such references remain valid. If someone tries to delete or rename the tag, Tagref will complain. More precisely, it checks the following:

1. References actually point to tags. A tag cannot be deleted or renamed without updating the references that point to it.
2. Tags are distinct. There is never any ambiguity about which tag is being referenced.
