+Operation to be applied to the vercode obtained by the defined @code{Update
+Check Mode}. @code{%c} will be replaced by the actual vercode, and the whole
+string will be passed to python's @code{eval} function.
+
+Especially useful with apps that we want to compile for different ABIs, but
+whose vercodes don't always have trailing zeros. With @code{Vercode Operation}
+set at something like @code{%c*10 + 4}, we will be able to track updates and
+build three different versions of every upstream version.
