 to decide what files need to be copied. This utility looks at the md5
 hash of the file contents.
 
-* How does aws-s3-sync-by-hash do it?
+* Usage
 
-The following is a rough, first draft, pseudo-scala, impression of the process.
+#+begin_example
+s3thorp
+Usage: S3Thorp [options]
 
-** constructor
+  -s, --source <value>  Source directory to sync to S3
+  -b, --bucket <value>  S3 bucket name
+  -p, --prefix <value>  Prefix within the S3 Bucket
+#+end_example
 
-val options = Load command line arguments and AWS security keys.
+* TODO
 
-** def sync(): Promise[Upload]
-
-val uploadPromise = createUploadPromise()
-if options contains delete then createDeletePromise()
-else return uploadPromise

-** def createUploadPromise(): Promise[Upload]
