SDMetrics stores the user's preferences in a file
.SDMetricsXYZ.props in the user's home directory. XYZ
indicates the program version. You can find the precise location of
the user preferences file in the "About" dialog (select
"Help -> About"). Quit SDMetrics and delete this file.
Delete the SDMetrics installation directory you created during
the installation, and all of its contents.
This completely removes SDMetrics from your system.
