  * BackupFiles used for manipulating (naming rolling/deleting) backup/version files when an alignment or project file is saved.
  * User configurable options are:
  * BACKUPFILES_ENABLED - boolean flag as to whether to use this mechanism or act as before, including overwriting files as saved.
- * The rest of the options are now saved as BACKUPFILES_PRESET, BACKUPFILES_SAVED and BACKUPFILES_CUSTOM
- * (see BackupFilesPresetEntry)
+ * BACKUPFILES_SUFFIX - a template to insert after the file extension.  Use '%n' to be replaced by a 0-led SUFFIX_DIGITS long integer.
+ * BACKUPFILES_NO_MAX - flag to turn off setting a maximum number of backup files to keep.
+ * BACKUPFILES_ROLL_MAX - the maximum number of backupfiles to keep for any one alignment or project file.
+ * BACKUPFILES_SUFFIX_DIGITS - the number of digits to insert replace %n with (e.g. BACKUPFILES_SUFFIX_DIGITS = 3 would make "001", "002", etc)
+ * BACKUPFILES_REVERSE_ORDER - if true then "logfile" style numbering and file rolling will occur. If false then ever-increasing version numbering will occur, but old files will still be deleted if there are more than ROLL_MAX backup files. 
+ * BACKUPFILES_CONFIRM_DELETE_OLD - if true then prompt/confirm with the user when deleting older backup/version files.
