Usage: fleet [filters] <git-args...>

Filters (same as parse-repos.sh):
  --simulation        Only simulation repositories
  --no-simulation     Only non-simulation repositories
  --type TYPE         Filter by repos.json type field
  --status STATUS     Filter by status (active|template|draft|wip|archived)
  --lineage LINEAGE   Filter by lineage (original|phet|naap)
  --catalog PATH      Override path to repos.json
  -h, --help          Show this help

Examples:
  fleet push
  fleet pull --ff-only
  fleet status -s
  fleet fetch --all --prune
  fleet --simulation log -1 --oneline
  fleet --type tool branch -vv
