# This RUN will install known Perl dependencies ahead of the automatic 
# installation by with `dzil authordeps` and `dzil listdeps` (below). Adding this 
# RUN  will cache these in a Docker layer makes the build much faster you have 
# only made a change in the Bio-VertRes-Config repo (just a one-line change 
# triggers the COPY command below and causes all the Perl dependencies to be 
# reinstalled).
# *But* it will make the image larger, and could in future install packages that
# are no longer required.
# => NOT recommended for production builds
