+ * Some utility routines for writing tests.
+ *
+ * Here are a variety of utility routines for writing tests compatible with
+ * the TAP protocol. All routines of the form ok() or is*() take a test
+ * number and some number of appropriate arguments, check to be sure the
+ * results match the expected output using the arguments, and print out
+ * something appropriate for that test number. Other utility routines help in
+ * constructing more complex tests, skipping tests, reporting errors, setting
+ * up the TAP output format, or finding things in the test environment.
+ *
+ * This file is part of C TAP Harness. The current version plus supporting
+ * documentation is at <http://www.eyrie.org/~eagle/software/c-tap-harness/>.

+ * Run a set of tests, reporting results.
+ *
+ * Usage:
+ *
+ * runtests [-b <build-dir>] [-s <source-dir>] <test-list>
+ * runtests -o [-b <build-dir>] [-s <source-dir>] <test>
+ *
+ * In the first case, expects a list of executables located in the given file,
+ * one line per executable. For each one, runs it as part of a test suite,
+ * reporting results. Test output should start with a line containing the
+ * number of tests (numbered from 1 to this number), optionally preceded by
+ * "1..", although that line may be given anywhere in the output. Each
+ * additional line should be in the following format:
+ *
+ * ok <number>
+ * not ok <number>
+ * ok <number> # skip
+ * not ok <number> # todo
+ *
+ * where <number> is the number of the test. An optional comment is permitted
+ * after the number if preceded by whitespace. ok indicates success, not ok
+ * indicates failure. "# skip" and "# todo" are a special cases of a comment,
+ * and must start with exactly that formatting. They indicate the test was
+ * skipped for some reason (maybe because it doesn't apply to this platform)
+ * or is testing something known to currently fail. The text following either
+ * "# skip" or "# todo" and whitespace is the reason.
+ *
+ * As a special case, the first line of the output may be in the form:
+ *
+ * 1..0 # skip some reason
+ *
+ * which indicates that this entire test case should be skipped and gives a
+ * reason.
+ *
+ * Any other lines are ignored, although for compliance with the TAP protocol
+ * all lines other than the ones in the above format should be sent to
+ * standard error rather than standard output and start with #.
+ *
+ * This is a subset of TAP as documented in Test::Harness::TAP or
+ * TAP::Parser::Grammar, which comes with Perl.
+ *
+ * If the -o option is given, instead run a single test and display all of its
+ * output. This is intended for use with failing tests so that the person
+ * running the test suite can get more details about what failed.
+ *
+ * If built with the C preprocessor symbols SOURCE and BUILD defined, C TAP
+ * Harness will export those values in the environment so that tests can find
+ * the source and build directory and will look for tests under both
+ * directories. These paths can also be set with the -b and -s command-line
+ * options, which will override anything set at build time.
+ *
+ * Any bug reports, bug fixes, and improvements are very much welcome and
