# Builds an already-generated set of API libraries, as specified
# by command-line arguments. The libraries to build can be
# specified as multiple arguments (one per library), or as a single
# file containing a list of files/directories, using the "@" prefix.
# Each file/directory should be one of:
# - A project file
# - A directory containing a project
# - A JSON file - the Discovery doc for the service to be built
#
# Common examples:
#
#   In autorelease.sh:
#   ./BuildGenerated @tmp/ApisToGenerate.sh
#
#   After regenerating everything:
#   ./BuildGenerated.sh DiscoveryJson/*.json
#
#   Just to build all projects that currently exist:
#   ./BuildGenerate.sh Src/Generated/*

set -e

# Final output directory of NuPkgs.
