# Generates *.java files from *.proto files.
#
# Q : Why genproto.gypi cannot be used ?
# A : --java_out option of protoc command needs .proto file to have all type
# names and *file name* uniquely or add special description inside .proto file.
# For exmaple, 'Command' type inside 'Command.proto' is forbidden.
# Thus if genproto.gypi is modified to have --java_out option,
# *all* .proto files have to be changed its name
# or be added special description.
#
# Q : Why rule based description like genproto.gypi cannot be used ?
# A : protoc command outputs generated .java files into an appropriate path
# based on its package name.
# The destination path cannot be detected at 'rules' section
# because the package name is described only in the .proto file
# so that 'outputs' section cannot be filled.
#
# We can retrieve Java package names from .proto files and automate the code
# generation. However, we need only a few proto files so far and it wouldn't
# be worth doing for now.
