+# dolphin-ftp-share - Manage FTP folder shares for Dolphin
+#
+# Usage:
+#   dolphin-ftp-share info                              List all shares
+#   dolphin-ftp-share add <name> <path> <anon> <acl>    Add/update a share
+#   dolphin-ftp-share delete <name>                     Remove a share
+#
+# Share configs are stored in ~/.local/share/dolphin-ftp-shares/
+# Shares are bind-mounted into ~/.local/share/dolphin-ftp-root/
+#
+# The FTP root directory can be served by any FTP server (e.g. vsftpd).
+# Each share appears as a real subdirectory under the FTP root via bind mount.
