backup-name: preference variable

Default value: "%p%b.bak"

If you've set want-backups nonzero, telling Epsilon to make a backup whenever it saves a file, Epsilon uses this variable to construct the name of the backup file. The variable contains a template, which Epsilon copies, substituting pieces of the original file for codes in the template, as follows (examples are for the file c:\dos\read.me):

%p
The original file's path (c:\dos\).

%b
The base part of the original file name (read).

%e
The extension of the original file name (.me).

%f
The full name of the original file (c:\dos\read.me).

%r
The name of the file relative to the current directory. (read.me if the current directory is c:\dos, dos\read.me if the current directory is c:\, otherwise c:\dos\read.me).

%x
The full pathname of the directory containing the Epsilon executable.

%X
The full pathname of the directory containing the Epsilon executable, after converting all Windows long file names to their equivalent short name aliases.

By default, Epsilon renames the old file so it has extension ".bak".
