### list packages are built

## usage: fx list-packages [--base|--cache|--universe]
##
## list-packages lists the packages that the build is aware of. These are
## packages that can be rebuilt, and/or pushed to a device.
## Note: list-packages DOES NOT list all packages that could be built, only
## those which are included in the current build configuration.
##
##   --base      - list only packages in base
##   --cache     - list only packages in cache
##   --universe  - list all packages
##
## See https://fuchsia.googlesource.com/fuchsia/+/master/docs/build/boards_and_products.md
## for more information about using these package sets.
