<!-- ABOUT THE PROJECT -->
## About The Project

+ Run docker-runcheck to validate your Dockerfile before attempting time-intensive docker builds. 

+ docker-runcheck works as follows:
  + looks for a file name Dockerfile in the current working directory
  + contructs one or more containers based on the mentioned parent image
  + docker image is downloaded if not present
  but it is not built.
  + export image as tar file and compile a list of the available binaries in the image
  + compile a list of any binaries mentioned in a RUN command that are  missing from the image or are used before being installed by a package manager.
