Always room for a new write stream ===================================== * E-mail: blflatex@gmail.com * Released under the LaTeX Project Public License v1.3c or later See http://www.latex-project.org/lppl.txt The morewrites package silently hooks into the TeX primitives responsible for writing to files to lift the restriction on the number of files open at the same time (16). Load the package with `\usepackage{morewrites}` as early as possible to avoid the `No room for a new \write ` error.
