Add snap packaging

dist/snap/README.md

@@ -0,0 +1,29 @@
+Snap is a cross-distribution packaging format for Linux. See
+https://snapcraft.io for more information.
+
+How to build
+------------
+Just type
+```
+snapcraft
+```
+from the *parent* directory: that is, not from the directory containing this
+README file, but from its parent directory. This snap has been successfully
+built in Ubuntu 16.04; more recent Ubuntu versions should work as well. Note
+that, regardless of the environment used to build it, the generated snap
+package will work on any distribution where snap is installed.
+
+How to test the snap
+--------------------
+The generated snap can be installed by typing
+```
+snap install --dangerous ./mvs-texturing*.snap
+```
+The `--dangerous` flag is needed because the snap has not been verified by the
+store.
+
+How to upload the snap to the store
+-----------------------------------
+A thorough guide can be found at the [snapcraft.io
+site](https://snapcraft.io/docs/build-snaps/publish).
