<module-spec> allows one to select modules or profiles a
particular operation should work on.
It is in the form of NAME:STREAM:VERSION:CONTEXT:ARCH/PROFILE and
supported partial forms are the following:
• NAME
• NAME:STREAM
• NAME:STREAM:VERSION
• NAME:STREAM:VERSION:CONTEXT
• all above combinations with ::ARCH (e.g. NAME::ARCH)
• NAME:STREAM:VERSION:CONTEXT:ARCH
• all above combinations with /PROFILE (e.g. NAME/PROFILE)
In case stream is not specified, the enabled or the default
stream is used, in this order. In case profile is not specified,
the system default profile or the 'default' profile is used.
