cg-tag will try to sign the tag if you give it the -s option. You can override the default key choice by passing it the -k argument.

Takes the tag name and optionally the associated ID as arguments.

-d DESCRIPTION

Description of the tag.

-k KEYNAME

Use the given key to sign the tag, instead of the default one. You can use any key identifier GPG recognizes - the argument is passed verbatim as the --default-key argument to GPG.

-s

Sign the tag by your private key using GPG.

OBJECT_ID

This is most usually the ID of the commit to tag. Tagging other objects than commits is possible, but rather "unusual".

-h, --help

Print usage summary.

--long-help

Print user manual. The same as found in cg-tag(1).
