+This build was listed as "orphaned - no maintainer" for a while.
+
+I thought it would be nice to update it for the latest version of
+TeighaViewer, which supports x86_64. Unfortunately, the latest version
+segfaults with an unhelpful error message, and all attempts to find a
+solution have been fruitless. Google searches show Ubuntu users having
+the same problem, meaning TeighaViewer 19.5.0.0 doesn't even work on the
+platform it's intended for (Ubuntu). So I'm sticking with 4.00.0 for now,
+meaning this is still a 32-bit-only build.
+
+The download site only has the latest version, but I was able to find
+several older versions (newer than 4.00.0) on web.archive.org and test
+them. These didn't crash, but they also didn't *work*: none of them
+would actually render anything. These versions all use qt5, and were
+built against older qt5 releases (5.3.x), so the problem might be qt5
+incompatibility... only the qt4 32-bit-only version works :(
+
+I'm listing myself as maintainer, but unless there's a new version of
+TeighaViewer that actually works, I won't be upgrading this build.
