# Depend on this library to enable fully-stamped build information in the
# version API provided by `:version`. This doesn't provide the API, it injects
# an override of stamped versions of the data.
#
# Note that depending on this will significantly reduce build caching with
# `--stamp` builds. It should be used sparingly, typically in user-facing
# binaries or systems that need to render a maximally detailed version string
# with build information stamped into it.
