The trouble with talking about WebKitGTK is that besides
libwebkit2gtk-* there are also a couple of packages like
libwebkitgtk3.0-cil that look as if they'd be relevant to this but
aren't.  Maybe we should only mention "webkit2gtk", which turns out
after all to be fairly transparently connected to the name of the main
library packages it builds (even if the -gtk2 suffix on one of them is
a bit mystifying).

I was thinking about mentioning both

        dpkg -l | grep -i webkit2gtk

and     grep sse2 /proc/cpuinfo

or combining them and saying to check if you get any output from

        grep -q sse2 /proc/cpuinfo || dpkg -l | grep -i webkit2gtk

But maybe that's going too far.

It looks like the only way I'd have that is if I had manually
installed it to support some sort of local JavaScript GUI, and I'm
hoping I would remember writing one of those.

Maybe "Webkit2gtk", or then again maybe just "WebKit".

JBR     with qualifications in linguistics, experience as a Debian
        sysadmin, and probably no clue about this particular package
