The deepModules hacks in the build system were added to support the long
paths that resulted from npm2, but npm3 fundamentally addresses that
problem, so deepModules is no longer necessary. In practical terms, npm3
shouldn't ever cause path lengths to become so long that they trigger
path length problems on certain operating systems.
The default behavior of the build task is to now apply the -snapshot
suffix dynamically rather than us manually hardcoding and managing it
within the source code itself. The `--release` flag will drop the
-snapshot suffix on a build, which should be used for any release
candidate.
The default behavior of the build task has also changed to create
rpm/deb packages as well. Since we've only confirmed that this works on
linux, you can override that behavior by passing `skip-os-packages`.
If you do not want to create any zip or tar.gz archives, you can pass
`--skip-archives`.
