Short: "Creates virtualized packages to simplify multi-API Version applications.",
Long: `A profile is a virtualized set of packages, which attempts to hide the
complexity of choosing API Versions from customers who don't need the
flexiblity of separating the version of the Azure SDK for Go they're employing
from the version of Azure services they are targeting.
"profileBuilder" does the heavy-lifting of creating those virtualized packages.
Each of the sub-commands of profileBuilder applies a different strategy for
choosing which packages to include in the profile.
