if (FALSE) {
Mtmp<-mvl_open("tmp_a.mvl", append=TRUE, create=TRUE)
mvl_write_object(Mtmp, runif(100), "vec1")
L<-list()
L[["x"]]<-mvl_write_object(Mtmp, 1:5)
L[["y"]]<-mvl_write_object(Mtmp, c("a", "b"))
L[["df"]]<-mvl_write_object(Mtmp, data.frame(x=1:100, z=runif(100)))
mvl_write_object(Mtmp, L, "L")
Mtmp<-mvl_remap(Mtmp)
print(Mtmp$L)
