This has been in the code-base for some months but I haven't found time to write it up yet. I'll try to get to that before long, but in the meantime here's an example, from the .spec file for the PPtest package: label = Phillips-Perron test menu-attachment = MAINWIN/Variable/URTests gui-main = GUI_PP This offers a menu item named "Phillips-Perron test" (from the "label" field), to appear at MAINWIN/Variable/URTests. The "MAINWIN" bit, as you might imagine, just tells gretl we're talking about the main window menus. The path "Variable/URTests" is constructed based on the UI definition file gretlmain.xml http://gretl.cvs.sourceforge.net/viewvc/gretl/gretl/gui2/gretlmain.xml?vi... Selecting the "Phillips-Perron test" menu item launches the package's "gui-main" function. Allin Cottrell
