- * KaTeX mhchem.js
- *
- * This file implements a KaTeX version of mhchem version 3.3.0.
- * It is adapted from MathJax/extensions/TeX/mhchem.js
- * It differs from the MathJax version as follows:
- * 1. The interface is changed so that it can be called from KaTeX, not MathJax.
- * 2. \rlap and \llap are replaced with \mathrlap and \mathllap.
- * 3. Four lines of code are edited in order to use \raisebox instead of \raise.
- * 4. The reaction arrow code is simplified. All reaction arrows are rendered
- * using KaTeX extensible arrows instead of building non-extensible arrows.
- * 5. \tripledash vertical alignment is slightly adjusted.
- *
- * This code, as other KaTeX code, is released under the MIT license.
- *
- * /*************************************************************

- * Implements the \ce command for handling chemical formulas

- *
- * KaTeX mhchem.js
- *
- * This file implements a KaTeX version of mhchem version 3.3.0.
- * It is adapted from MathJax/extensions/TeX/mhchem.js
- * It differs from the MathJax version as follows:
- * 1. The interface is changed so that it can be called from KaTeX, not MathJax.
- * 2. \rlap and \llap are replaced with \mathrlap and \mathllap.
- * 3. Four lines of code are edited in order to use \raisebox instead of \raise.
- * 4. The reaction arrow code is simplified. All reaction arrows are rendered
- * using KaTeX extensible arrows instead of building non-extensible arrows.
- * 5. \tripledash vertical alignment is slightly adjusted.
- *
- * This code, as other KaTeX code, is released under the MIT license.
- *
- * /*************************************************************
- *
- * MathJax/extensions/TeX/mhchem.js
- *
- * Implements the \ce command for handling chemical formulas
- * from the mhchem LaTeX package.
