Entry point a la "git" or "go"

[Andrei Alexandrescu via Digitalmars-d]

There's this recent trend seen with git and go - all tooling is entered 
by a single command.

Are there advantages to doing the same for our toolchain? (Consider 
it'll include things such as dub, dfix, and dformat in the future.) 
Something like "dc", a program that parses the command line and 
dispatches it to the appropriate tool(s).

How would this add value to our toolchain?
