# Performs steps to tag a release.
#
# Steps:
#   Create the "release" commit:
#     - CMakeLists.txt: Unset NVIM_VERSION_PRERELEASE
#     - CMakeLists.txt: Unset NVIM_API_PRERELEASE
#     - Tag the commit.
#   Create the "version bump" commit:
#     - CMakeLists.txt: Set NVIM_VERSION_PRERELEASE to "-dev"
#
# Manual steps:
#   - CMakeLists.txt: Bump NVIM_VERSION_* as appropriate.
#   - git push --follow-tags
