+I've added an arm build to the autobuilds in [[install/Linux_standalone]].
+
+It's somewhat experimental:
+
+* There are several arm architectures. This build is done on Debian armel,
+  which uses EABI. It will not work on older arm systems whose kernels
+  do not support EABI. (It's also little endian.)
+* It relies on the system having a compatable version of glibc installed.
+  This could be improved by finding a way to build a static binary
+  (but glibc does not make that easy), or trick the linker into linking
+  against a glibc shipped in the bundle. The problem with the latter
+  is that glibc loads some support libraries at runtime.
+
+I'll be interested to hear if this is useful. If it seems sufficiently
+useful, I might try to add the webapp to the build, which would be somewhat
+complicated, but doable (since I'm building using qemu, it can run a build
+on amd64 first to get the TH splices).
