+ENVIRONMENT VARIABLES
+
+The Qt library recognizes a number of OS/2-specific environment variables that
+affect its functionality at runtime. The table below lists these variables and
+their meaning:
+
+  QT_PM_NO_SOUND_SHARE      If set, Qt will open the audio device in exclusive
+                            only one sound may be played on the computer at a
+                            time. This mode is recommended for some sound cards
+                            when using the Uniaud audio driver as it is known to
+                            have problems with simultaneous playback. In current
+                            Qt builds, this is the default behavior if neither
+                            this nor the QT_PM_SOUND_SHARE variable is set.
+
+  QT_PM_SOUND_SHARE         The opposite to the above. If set, Qt will open the
+                            audio device in shared mode. This variable is
+                            ignored if QT_PM_NO_SOUND_SHARE is set.
+
+  QT_PM_NO_REGISTRY         If set, Qt will not use the Open32 registry to store
+                            application settings with QSettings. Instead, plain
+                            text INI files will be used for both NativeFormat
+                            and IniFormat. Due to a number of problems in the
+                            Open32 registry implementation (that may easily lead
+                            to registry corruption), this is the default
+                            behavior if neither this nor the QT_PM_REGISTRY
+                            variable is set.
+
+  QT_PM_REGISTRY            The opposite to the above. If set, Qt will use the
+                            Open32 registry to store application settings.
