All-in-one build command

`./make-linux` clones and builds:

- arrow
- brotli
- lz4
- parquet
- snappy
- zlib
- zstd
- this project

as a statically linked binary. Two Boost libs are still pulled in as
shared libs, should probably fix that, too, for ultimate portability.

 You can fetch a version built for Ubuntu 16.04 at https://s3.amazonaws.com/cldellow/public/libparquet/libparquet.so.xz
 
+### Building
+
+```
+./make-linux
+```
+
+The first run will git clone a bunch of libraries, patch them to be statically linkable and build them.
+
+Subsequent builds will only build the parquet virtual table extension.

-## Building
-
-If you're a masochist, you can try to build this yourself:
-
-1. Install [`parquet-cpp`](https://github.com/apache/parquet-cpp)
-    1. Master appears to be broken for text row group stats; see https://github.com/cldellow/sqlite-parquet-vtable/issues/5 for which versions to use
-2. Run `./build-sqlite` to fetch and build the SQLite dev bits
-3. Run `./parquet/make` to build the module
-    1. You will need to fixup the paths in this file to point at your local parquet-cpp folder.
