Uuseg is an OCaml library for segmenting Unicode text. It implements the

breaking algorithm to detect line break opportunities.

vcsh: bump version to 1.20141026
vcsh: add ttuegel as maintainer
Merge branch 'vcsh'
Update elm to 0.14.

Note that elm has a different package split: The old Elm 0.13 package
is now elm-compiler, elm-make and elm-package.

Instead of invoking "elm" one now has to use "elm-make".

I kept the 0.13 version of elm around in case someone depends
on it.
