lib/mustache/readme_moodle.txt says:

Clone from https://github.com/moodle/custom-mustache.php
Rebase onto latest tag from https://github.com/bobthecow/mustache.php

Yet, on 3.1, if I do..

wget https://github.com/bobthecow/mustache.php/archive/v2.10.0.tar.gz

tar -xzvf v2.10.0.tar.gz

rm -R lib/mustache/src/

$  mv mustache.php-2.10.0/src/ lib/mustache/

There are no differences. (Same applies to 3.2 and v2.11.1).

So either:

• We are missing some commits (and have a broken functionality for multiple releases)
• The readme_moodle.txt is outdated and needs to be fixed

The status of https://github.com/moodle/custom-mustache.php is really unclear. Which branch do you rebase and so on?

This needs sorting out
