    -    The script is designed to extract function signatures that match a
    -    specific pattern derived from the unit test file's name.
    -    `generate-clar-decls.sh` does not pick up dashes in filenames, which
    -    prevents the scripts from being run.
    +    "generate-clar-decls.sh" script is designed to extract function
    +    signatures that match a specific pattern derived from the unit test
    +    file's name. The script does not know to massage file names with dashes,
    +    which will make it search for functions that look like, for example,
    +    `test_mem-pool_*`. Having dashes in function names is not allowed
    +    though, so these patterns won't ever match a legal function name.
     
         Adapt script to translate dashes (`-`) in test suite filenames to
         underscores (`_`) to correctly extract the function signatures and run
