# This script is used make sure that all macros which gregoriotex-write.c
# might write to a gtex file are defined in the TeX code.
# It does this by creating two lists: one of all the \Gre macros defined in the TeX
# code, and one of all the macros which might be printed by gregoriotex-write.c.
# It then compares these two lists and outputs res.tex which contains a list of
# undefined macros (preceded by >) and macros which are defined but cannot be
# produced by gregoriotex-write.c

# It is not perfect, and especially has trouble with macros whose names
# gregoriotex-write.c builds a piece at a time.
