| // This binary fetches all repos for a user from gitlab. | ||
| // | ||
| // It is recommended to use a gitlab personal access token: | ||
| // https://docs.gitlab.com/ce/user/profile/personal_access_tokens.html. This | ||
| // token should be stored in a file and the --token option should be used. | ||
| // In addition, the token should be present in the ~/.netrc of the user running | ||
| // the mirror command. For example, the ~/.netrc may look like: | ||
| // | ||
| // machine gitlab.com | ||
| // login oauth | ||
| // password <personal access token> | ||
