+  Abstract:
+    This example shows how to read the custom data of an .lpi file and
+    how to change it. The .lpi file is given as first command line parameter.
+  
+    For example:
+      ./lpicustomdata lpicustomdata.lpi
+
+      This will show the old custom data, change a value and save it.
+      If there was no custom data in the .lpi file, there will be no output.
+      
+    Important:
+      The IDE does not read the .lpi file if it changed on disk.
+      If you add custom data, make sure the IDE has not this project open.
+
