# Eventual goals:
#
# - Check validity of tests fillers.
# - Filter test fillers based on properties.
# - Convert between various test filler formats.
# Non-goals:
#
# - Test filling.
# - Test post-state checking.
# Current goals:
#
# - Generate GeneralStateTests from VMTests.
# Input:
#
# - VMTest filler directory/name, without suffix Filler.json
# eg. vmArithmeticTest/add0
# Output:
