s3thorp
Synchronisation of files with S3 using the hash of the file contents.

Originally based on Alex Kudlick's aws-s3-sync-by-hash.
The normal aws s3 sync ... command only uses the time stamp of files
to decide what files need to be copied. This utility looks at the md5
hash of the file contents.
Usage
s3thorp
Usage: s3thorp [options]
-s, --source <value> Source directory to sync to S3
-b, --bucket <value> S3 bucket name
-p, --prefix <value> Prefix within the S3 Bucket
-i, --include <value> Include matching paths
-x, --exclude <value> Exclude matching paths
-v, --verbose <value> Verbosity level (1-5)
The --include and --exclude parameters can be used more than once.
Behaviour
When considering a local file, the following table governs what should happen:
| # | local file | remote key | hash of same key | hash of other keys | action |
| 1 | exists | exists | matches | - | do nothing |
| 2 | exists | is missing | - | matches | copy from other key |
| 3 | exists | is missing | - | no matches | upload |
| 4 | exists | exists | no match | matches | copy from other key |
| 5 | exists | exists | no match | no matches | upload |
| 6 | is missing | exists | - | - | delete |
Executable JAR
To build as an executable jar, perform `sbt assembly`
This will create the file `cli/target/scala-2.12/s3thorp-assembly-$VERSION.jar` (where $VERSION is substituted)
Copy and rename this file as `s3thorp.jar` into the same directory as the `bin/s3throp` shell script.
