GnuPG key for signing. The configuration variable `gpg.program`
is used to specify custom GnuPG binary.
Tag objects (created with `-a`, `s`, or `-u`) are called "annotated"
tags; they contain a creation date, the tagger name and e-mail, a
tagging message, and an optional GnuPG signature. Whereas a
"lightweight" tag is simply a name for an object (usually a commit
object).
Annotated tags are meant for release while lightweight tags are meant
for private or temporary object labels. For this reason, some git
commands for naming objects (like `git describe`) will ignore
lightweight tags by default.
