+        Your program might require some environment variable to be set
+	properly in order to run successfully.
+	In this case you need to set this environment variable in the
+	Linux shell, since Wine will pass on the entire shell environment
+	variable settings to the Windows environment variable space.
+	Example for the bash shell (other shells may have a different syntax
+	!):
+        <screen>
+	  export MYENVIRONMENTVAR=myenvironmentvarsetting
+	</screen>
+	This will make sure your Windows program can access the
+	MYENVIRONMENTVAR environment variable once you start your program
+	using Wine.
+	If you want to have MYENVIRONMENTVAR set permanently, then you can
+	place the setting into /etc/profile, or also ~/.bashrc in the case of
+	bash.
