### create and publish packages from a build directory

## usage: fx publish [--build-dir <DIR>] [--pkg-key <key file>]
##                   [--far-dir <DIR>] [--update-repo <DIR>] [pkg1 pkg2 ...]
##
## One or more package name arguments may be supplied as the last arguments.
## If no package name is supplied, all packages from the current build output
## will be published.
##
## optional arguments:
##   --build-dir          Directory containing the build output
##   --pkg-key            Key used to sign the package's meta FAR
##   --fars-dir           Directory to be used to build the meta FAR
##   --update-repo        Directory to be used to publish the meta FAR and
##                        associated content blobs
##   --mono-versions      Base the repository versioning on monotonically
##                        increasing values instead of time since epoch
