Supporting Files
JumpBack looks in the directory  ~/Library/JumpBack  for supporting files.  It copies sample template files from JumpBack.app if there are none in ~/Library/JumpBack. 

Predefined exemption patterns.
JumpBack reads a file called ~/Library/JumpBack/Patterns
which holds all of the patterns that will be exempted from the duplication.  The file consists of multiple patterns, with one per line.  Any changes to the exemption list, made in preferences, will automatically be saved. 

There are several special characters that can be used:
	$	Anchor pattern at the end of the line
	^	Anchor at the beginning of the line
	.	One character wildcard
	\	Remove special meaning of above characters

An example listing follows:

lost+found$
\.debug$
\.NeXTTrash$

Predefined JumpBack sessions
Jumpback reads the file ~/Library/JumpBack/Predefined
to build a menu of source and destination pairs.  Picking one of these pairs in that menu causes a JumpBack window to be built with those files in the source and destination boxes.  

The file contains one line per pairing with three tab separated columns for each line.  The first column is the menu title, the second is the source directory and the third column is the destination directory.  Lines beginning with the '#' character will be treated as comments. An example file follows.

# this is a comment line
Save Home to OD	~	~/OD
Restore OD to Home	~/OD	~
