'''Generates a test suite from NIST PKITS test descriptions.

The output is a set of Type Parameterized Tests which are included by
pkits_unittest.h. See pkits_unittest.h for information on using the tests.
GoogleTest has a limit of 50 tests per type parameterized testcase, so the tests
are split up by section number (this also makes it possible to easily skip
sections that pertain to non-implemented features).

Usage:
  generate_tests.py <PKITS.pdf> <output.h>
