# Generates C# source files from .proto files.
# You first need to make sure protoc has been built (see instructions on
# building protoc in root of this repository)

# This script performs a few fix-ups as part of generation. These are:
# - descriptor.proto is renamed to descriptor_proto_file.proto before
#   generation, to avoid the naming collision between the class for the file
#   descriptor and its Descriptor property
# - This change also impacts UnittestCustomOptions, which expects to
#   use a class of Descriptor when it's actually been renamed to
#   DescriptorProtoFile.
# - Issue 307 (codegen for double-nested types) breaks Unittest.proto and
#   its lite equivalents.
