## The following statement keeps this script from completing,
## so that the script can be tested --- with output to stdout and
## stderr showing in a terminal --- when using Nautilus
## 'Open > Run in a Terminal'. NOTE: Since xpg runs as a 'background'
## process, the terminal window would, without the statement below,
## immediately close after xpg shows the file. (Also could use 'xpg -f'.)
##
## Comment this line, to deactivate it.
