Due to historical reasons, the code is in subfolder "1". With SVN removal, we place the code back and remove the annoying "1" folder.

<p>Simple mode that tries to handle APL as well as it can.</p>
|
||
<p>It attempts to label functions/operators based upon
|
||
monadic/dyadic usage (but this is far from fully fleshed out).
|
||
This means there are meaningful classnames so hover states can
|
||
have popups etc.</p>
