13// This binary fetches all repos for a user from gitlab.
14//
15// It is recommended to use a gitlab personal access token:
16// https://docs.gitlab.com/ce/user/profile/personal_access_tokens.html. This
17// token should be stored in a file and the --token option should be used.
18// In addition, the token should be present in the ~/.netrc of the user running
19// the mirror command. For example, the ~/.netrc may look like:
20//
21// machine gitlab.com
22// login oauth
23// password <personal access token>
