.SH WINDOW TITLE
The window title can be replaced with the output of a user-provided script,
which is called by nsxiv whenever there's a redraw. The path of this script is
.I $XDG_CONFIG_HOME/nsxiv/exec/win-title
and the arguments given to it (where "Optional" arguments might be empty) are:
1) resolved absolute path of the current file,
2) current file number,
3) total file count,
4) image width (Optional: Disabled on thumbnails mode),
5) image height (Optional: Disabled on thumbnails mode),
6) current zoom (Optional: Disabled on thumbnails mode).
.P
The term file is used rather than image as nsxiv does not precheck that the
input files are valid images. Total file count may be different from the actual
count of valid images.

There is also an example script installed together with nsxiv as
.IR EGPREFIX/win-title .
