# Here's the score, kids. There are a few different places from which we can
# get packages. In priority order, they are:
#
# The CGTS packages we've built ourselves
# The CGTS packages that Jenkins has built (coming soon to a script near you)
# The CentOS packages in various repos
# - Base OS
# - OpenStack Repos
# EPEL (Extra Packages for Enterprise Linux)
#
# This script can function in two ways:
# If you specify a filename, it assumes the file is a list of packages you
# want to install, or dependencies you want to meet. It installs whatever
# is in the list into current directory. Failure to find a dependency
# results in a return code of 1
#
# If no file is specified, we generate a file ($DEPLISTFILE) of dependencies
# based on current directory
#
# We then continuously loop through generating new dependencies and installing
# them until either all dependencies are met, or we cannot install anymore
#
# We also log where dependencies were installed from into
# export/dist/report_deps.txt
#
# This function generates a simple file of dependencies we're trying to resolve

# Takes a list of requirements (either explcit package name, or capabilities
# to provide) and install packages to meet those dependancies
#
# We take the list of requirements and first try to look them up based on
# package name. If we can't find a package with the name of the requirement,
# we use --whatprovides to complete the lookup.
#
# The reason for this initial name-based attempt is that a couple of funky
# packages (notably -devel packages) have "Provides:" capabilities which
# conflict with named packages. So if explictly say we want "xyz" then we'll
# install the "xyz" package, rather than "something-devel" which has "xyz"
# capabilities.
