This file is used to provide persistent variables of a spell to another spell.
For example here's EXPORTS file from "xorg-server" spell:
which is used later in DEPENDS of "x11vnc" spell:
persistent_read xorg-server XORG_SERVER_OPTS XORG_SERVER_OPTS && if list_find "$XORG_SERVER_OPTS" "--enable-record"; then config_query_option X11VNC_OPTS \ "Enable xrecord extension support?" y \ "--with-xrecord" \ "--without-xrecord" fi
Note: since the variables are read from within a spell's tablet, don't forget to add a REPAIR^all^EXPORTS file if needed.
