Comment 12 for bug 1833752

Nope...I deleted the .js files I had plopped in /usr/share/SuperCollider/HelpSource/lib and did a reinstall of supercollider-common. The same issue appeared, and I found that symbolic links to the /usr/share/javascript directory were created:

Mar 5 01:56 codemirror-5.39.2.min.js -> ../../../javascript/codemirror/codemirror.js

Mar 5 01:56 codemirror-addon-simple-5.39.2.min.js -> ../../../javascript/codemirror/addon/mode/simple.js

Mar 5 01:56 jquery.min.js -> ../../../javascript/jquery/jquery.min.js

...however, only the jquery.min.js link points to an actual file. There is no 'codemirror' directory under /usr/share/javascript.
