Implement a Dockerfile.

Apparently it's quite common nowadays for people to use docker to build
and run software in a contained way, so provide users with the facility
they need in order to do that.

 ## Building a docker image
 
-We start with a `debian` image:
+A `Dockerfile` is provided, to use it:
 
-	docker run -it debian bash
+    docker build -t pgloader:debian .
+    docker run --rm --name pgloader pgloader:debian bash -c "pgloader --version"
 
-And then run the following steps:
+The `build` step install build dependencies in a debian jessie container,
+then `git clone` and build `pgloader` in `/opt/src/pgloader` and finally
+copy the resulting binary image in `/usr/local/bin/pgloader` so that it's
+easily available.

-Install a binary version on SBCL, which unfortunately has no support for
-core compression, so only use it to build another SBCL version from sources
-with proper options:
-
-    $ mkdir sbcl
-    $ cd sbcl
-    $ wget http://prdownloads.sourceforge.net/sbcl/sbcl-1.2.6-x86-64-linux-binary.tar.bz2
-    $ wget http://prdownloads.sourceforge.net/sbcl/sbcl-1.2.6-source.tar.bz2?download
-    $ mv sbcl-1.2.6-source.tar.bz2\?download sbcl-1.2.6-source.tar.bz2
-    $ tar xf sbcl-1.2.6-x86-64-linux-binary.tar.bz2
-    $ tar xf sbcl-1.2.6-source.tar.bz2
-    $ exit
-
-Install SBCL as root
-
-    # cd /home/dim/sbcl/sbcl-1.2.6-x86-64-linux
-    # bash install.sh
-
-Now back as the unprivileged user (dim) to compile SBCL from sources:
-
-    # su - dim
-    $ cd sbcl/sbcl-1.2.6
-    $ sh make.sh --with-sb-core-compression --with-sb-thread > build.out 2>&1
-    $ exit
-
-And install the newly compiled SBCL as root:
-
-    # cd /home/dim/sbcl/sbcl-1.2.6
-    # sh install.sh
-
-Now build pgloader from sources:
-
-    # su - dim
-    $ git clone https://github.com/dimitri/pgloader
-    $ cd pgloader
-    $ make
-    $ ./build/bin/pgloader --help
-    $ exit
-
-Now install pgloader in `/usr/local/bin` to make it easy to use:
-
-    # cp /home/dim/pgloader/build/bin/pgloader /usr/local/bin
-    # pgloader --version
-
-Commit the docker instance and push it, from the host:
-
-    $ docker login
-    $ docker ps -l
-    $ docker commit <id> dimitri/pgloader-3.1.cd52654
-    $ docker push dimitri/pgloader-3.1.cd52654
