Fix an issue noted by CRAN. Both notangle and noweave should return the name of the file that was created.
A nested construct such as [[ abc[[3]] <- 4]] would crash the routine.
Addition of LazyData: true, and a further punctuation change in the title field.
Slight change in the Title punctuation, at the request of CRAN
Revise the vignette. (Inspired by a talk by Donald Knuth at userR 2016.)
All code chunks are expected to have a name. Issue an error message if this is not so instead of dying.
Modify the package to work with the non-Sweave vignettes code of R 3.0. This allows the noweb document to be in the vignettes directory.
Various updates to the code as I test it.
