#ifndef _LIB_CACHE_RESCUE_H_
#define _LIB_CACHE_RESCUE_H_

/* This code handles the case where an old schematic was made before
 * various changes were made, either to KiCad or to the libraries, and
 * the project needs to be recovered. The function of note is a member
 * of SCH_EDIT_FRAME, defined thus:
 *
 * bool SCH_EDIT_FRAME::RescueProject( bool aSilentIfNone );
 *
 * When this is called, a list of problematic symbols is compiled. If
 * this list is empty, then the function displays a notification and returns
 * (if aSilentIfNone is true, the notification is silenced).
