## CROSS COMPILING TRANSMISSION 2.82 FOR WD MY CLOUD ##
########################################################

This is a guide to compile transmission 2.82 for the WD MyCloud 2/3/4 TB.

Because I didn't want to install the build tools and dependencies on my NAS I chose to
setup a cross-compiler toolchain on my x86_64 Ubuntu 12.04 machine and create a .deb package
that can be installed on the NAS. Furthermore the cross compiler can be used to compile anything for the My Cloud (printer drivers, etc.)

Docker Registry S3 cleanup script

This simply requires you to install the boto3 package and set the DOCKER_BUCKET variable to point at the bucket you would like to clean up, and the rest should be handled automatically. That's is presuming you have credentials to manage the S3 bucket in one of the default locations where Boto go to look for them.

Since the script more or less traverses through your entire S3 bucket, it probably makes sense to only run it infrequently, like daily or weekly, depending on the amount of repositories and layers you have and the amount of updates on the registry in total.
