+# tex-shell
+
+A [flake-parts](https://flake.parts/) module for building a devShell equipped with LaTeX.
+For a significantly more sophisticated implementation, see [latex-utils](https://github.com/jmmaloney4/latex-utils).
+
+The point of this simple flake-parts module is to give you a devShell with texlive along with a `latexmk` wrapped with a `.latexmkrc` file.
+My use case is to get a texlive environment that works for interacting with a repo with a bunch of latex documents, e.g. class notes, homeworks and exams.
