>Description:
Reinstalling or upgrading sysutils/scanbuttond will overwrite user-modified config .sh files in /usr/local/etc/scanbuttond/.

This patch changes the port to work like other ports.  If there are user .sh files present, they are left alone.  If not present, sample files are installed.
The patch is based on sysutils/apcupsd, which seemed to be the right way to do it.


>How-To-Repeat:
Modify /usr/local/etc/scanbuttond/buttonpressed.sh initscanner.sh.
Reinstall the port.  Notice the modified files have been replaced with sample files from the port.
>Fix:
Apply patch.
