-//! pvm_exec is a proxy/wrapper command to run compilation task remotely. The most important task
-//! for this program is to run a `fd_server` that serves remote file read/write requests.
-//!
-//! It currently works as a command line wrapper to make it easy to schedule an existing dex2oat
-//! task to run in the VM.
-//!
-//! Example:
-//! $ adb shell exec 3</input/dex 4<>/output/oat ... pvm_exec --in-fd 3 --out-fd 4 -- dex2oat64 ...
-//!
-//! Note the immediate argument "dex2oat64" right after "--" is not really used. It is only for
-//! ergonomics.
