\e[1;37mREMARKS:\e[0m
  \e[32mupdate\e[0m:
    The copy must have a valid answers file which contains info from the last Copier execution,
    including the source template (specified with the key \`_src_path\`).
    If the \`\e[34mproject_path\e[0m\` is a Git repository and the answer file defines a \`_commit\`, Copier will
    do its best to respect the diff that you have generated since the last execution. To disable
    that, use \`\e[36m--no-diff\e[0m\`.

  \e[34mtemplate_src\e[0m:
    Shortcut URLs are of the form \`platform:namespace/project\`.
    Supported platforms are: \`gh\` for GitHub and \`gl\` for GitLab.

  \e[36m-r, --vcs-ref\e[0m:
    If you do not specify it, it will try to checkout the latest git tag, as sorted using the PEP
    440 algorithm. If you want to checkout always the latest version, use \`--vcs-ref=HEAD\`.
