Update / delete FindVariableUsedInExternalCalls.py
This is the page that documents the script. Thank you.
Moreover, if the script really does what his name indicates, it could be replaced by a function in ImplementRPEtoSources, since the variable used in external calls could be identified when identifying external subprogram calls.
The script was taking as input clean_preprocessed_sources and the vault generated with ImplementRPEtoSources: I don't know how the inconsistency btw the type of variables was managed. Maybe he was using a vault generated by makevault.
But I think that the purpose is: to list the rpe variables used in external call, because their value cannot be changed; this can be achieved just with the vault generated buy ImplementRPEtoSources.
