FIPS tools explained ==================== api_list.pl a script to produce an API description, saying what parameters are for input, output or both. Most often, the direction of a parameter is determined automatically. However, quite a number of them are educated guesses. Either way, the information is stored in the file declarations.dat in this directory, and can be manually corrected; simply go through declarations.dat, look for any value with the key 'direction' where the value contains a question mark. Those should be changed to whatever is true, and the values should be one of the following: <- output -> input <-> both api_fns.pm a module that helps api_list.pl do its job. declarations.dat a file of information about public fips symbols. See api_list.pl above.
