This might no longer be needed at all; unclear.

Currently just a wrapper for `bc -ql`.

I was tired of thinking I'd come up with a tag but not being able to find
it in the existing page set.

There's some glitchiness here.

They added a bunch of extra links to the thing I was just dumping out
in Lynx, so I decided to check if there's an easy enough API to work with.

I don't really remember why I wrote this.

Uses middot for tab extents, and an extends/precedes for stuff that goes
off the screen.

I don't think this works the way you'd want.

This is useful for performance reasons at times.  Folding code is super
slow.
