| # This script is taken from: https://github.com/rekka/latex-flatten | |
| # A simple script for flattening LaTeX files by inlining included files. | |
| # | |
| # - Supports `\include` and `\input` commands. | |
| # - Automatically adds extension `.tex` if the file does not have an extension. | |
| # - Handles multiple include commands per line, comments. | |
| # - Does not flatten recursively. | |
