man.th.extra2.suppress boolean man.th.extra2.suppress Suppress extra2 part of header/footer? 0 If the value of man.th.extra2.suppress is non-zero, then the extra2 part of the .TH title line header/footer is suppressed. The content of the extra2 field is usually displayed in the left footer of the page and is typically "source" data, often in the form Name Version; for example, "GTK+ 1.2" (from the gtk-options(7) man page). You can use the refentry.source.name.suppress and refentry.version.suppress parameters to independently suppress the Name and Version parts of the extra2 field.
