Instead of reading the arguments from sys.stdin, which requires
that stdin is setup properly for that in the runner, use the new
api.arguments() method to directly fetch the arguments.
Also fix missing newlines between imports and methods to be more
PEP-8 complaint, where needed.
The `capture_output` argument for subprocess.run was added in 3.7,
but want to support 3.6 as well. Change all the usages of it with
`stdout=subprocess.PIPE` that will have the same effect, at least
for stdout.
For all currently supported modules, i.e. stages and assemblers,
convert the STAGE_DESC and STAGE_INFO into a proper doc-string.
Rename the STAGE_OPTS into SCHEMA.
Refactor meta.ModuleInfo loading accordingly.
The script to be used for the conversion is:
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---

Add a new assembler that takes a tree and creates a Open Container
Initiative[2] image according to the OCI image format[2]. The final
result is a tarball, aka a "orci-archive", that can be pulled into
podman with `podman pull oci-archive:<archive>`. Currently the only
required options are `filename` and `architecture`.
