#!/usr/bin/env bash
# gitea-setup.sh — Initialize a local folder as a git repo and push to Gitea.
#
# Handles two cases:
#   A) Folder is already a git repo  → just create Gitea repo and push
#   B) Folder is not yet a git repo  → git init, stage all, commit, then push
#
# Usage:
#   ./gitea-setup.sh [options] [<repo-path>]
#
# Options:
#   -n, --name NAME        Gitea repo name          (default: directory name)
#   -d, --desc DESC        Repository description   (default: empty)
#   -o, --org  ORG         Create under organization instead of personal account
#   -p, --private          Create as private repo
#   -l, --login LOGIN      tea login profile        (default: active login)
#       --auto-push        Enable Gitea auto-push after sync-push.sh
#       --no-auto-push     Disable Gitea auto-push  (default)
#   -h, --help             Show this help
#
# Prerequisites:
#   - Gitea CLI (tea) installed and at least one login configured
#     (run 'tea login add' if not done yet)
