Before submitting a pull request, please remember to run make checklatex This should produce no output other than echoing the command that it is running. Currently, there are a number of problems with the document because this check was not made. I can correct some as editor; one will be harder to fix (the inappropriate use of color in an example). None of these should have been accepted; we need to make this part of the CI test. But until that time, please manually run make checklatex ; you can do this in a chapter directory, for example: % cd chap-one-side % make checklatex ../getlatex --allowpageref --noquotechk *.tex % Thanks - this will help reduce problems with the standard.
