CarpetX documentation file uses extra LaTeX package

[Roland Haas]

Using extra packages (listing in this case) breaks the <config>-ThornGuide target which builds a single PDF file with all documentation (http://einsteintoolkit.org/usersguide/UsersGuide.html#x1-34000B3.3).

The only packages that may be used (and they don’t need a \usepackage) are those already required by cactus.sty:

$ grep RequirePackage repos/flesh/doc/latex/cactus.sty
\RequirePackage[utf8]{inputenc}
\RequirePackage{fancyhdr}
\RequirePackage{graphicx}
\RequirePackage{latexsym}
\RequirePackage{amssymb}
\RequirePackage{amsmath}
\RequirePackage{ifthen}
\RequirePackage{calc}
\RequirePackage{thumbpdf}
\RequirePackage{hyperref}

This patch removes the packages but does suffer from less pretty layout: git hash 337b3f8c "CarpetX: remove tabularx and listings from documentation" of CarpetX

[Roland Haas]

In today’s ET call it was decided to add lstlistings to the default Cactus packages if possible (ie if included in “base” typical LaTeX installation on macOS and Linux and if ok for the TeX to HTML conversion).

[Lucas Timotheo Sanches]

I report that the package listings.sty, which provides the lstlistings environment IS present on the texlive-base package of Ubuntu’s latest release.
