# This script installs the tools needed to automatically generate the
# code for a new service, together with their dependencies.
# In particular, it installs the pyang-swagger tool that is used to
# generate the swagger-compatible REST APIs and the swagger-codegen
# tool that is used to generate the service stub.
#
# In addition, this script installs the polycube-codegen application that
# can be used to interact with the aforementioned tools and generate the
# service stub and/or the REST APIs given the YANG model of the new service.
#
# Run the polycube-codegen application form the terminal after executing this
# script in order to get the needed information.
#
# The script will download the tools if they are not installed, while it will
# update those tools otherwise.
