# The testing package comes without the antlr jar or executable versions of BuildGrammar & TextModify
# - users download the first and build the others from source
# For V1 this script downloaded the JAR and the grammar-validator.yaml installed BuildGrammar from
# a nupkg as a dotnet tool called "csharpgrammar". TextModify was not required.
# For V2:
#  - Download the JAR to where the testing package expects.
#  - Leave the YAML to install BuildGrammar as a dotnet tool as before
#  - Create a BuildGrammar script which invokes "dotnet csharpgrammar"
#  - Create a TextModify script which does nothing - it is not used but santity checking looks for it

# Download the JAR
