"""gen_gtest_pred_impl.py v0.1 | |
Generates the implementation of Google Test predicate assertions and | |
accompanying tests. | |
Usage: | |
gen_gtest_pred_impl.py MAX_ARITY | |
where MAX_ARITY is a positive integer. | |
The command generates the implementation of up-to MAX_ARITY-ary | |
predicate assertions, and writes it to file gtest_pred_impl.h in the | |
directory where the script is. It also generates the accompanying | |
unit test in file gtest_pred_impl_unittest.cc. | |
