# Script for generating AOT snapshot using Dart 2 pipeline: Fasta with
# strong mode enabled, AOT specific Kernel-to-Kernel transformations and
# Dart VM precompiler with strong mode semantics and reified generics.
# Parse incoming arguments and extract the value of --packages option if any
# was passed. Split options (--xyz) and non-options into two separate arrays.
# All options will be passed to gen_snapshot, while --packages will be
# passed to Fasta.
