+=head1 DESCRIPTION
+
+F<Test.php> is an implementation of Perl's L<Test::More> for PHP. Like
+Test::More it produces language agnostic TAP output (see L<TAP>) which
+can then be gathered, formatted and summarized by a program that
+understands TAP such as prove(1).
+
+=head1 HOWTO
+
+First place the F<Test.php> in the project root or somewhere else in
+the include path where C<require> and C<include> will find it.
+
+Then make a place to put your tests in, it's customary to place TAP
+tests in a directory named F<t> under the root but they can be
+anywhere you like. Make a test in this directory or one of its subdirs
+and try running it with php(1):
+
+ $ php t/pass.t
+ 1..1
+ ok 1 This dummy test passed
+
+The TAP output consists of very simple output, of course reading
+larger output is going to be harder which is where prove(1) comes
+in. prove is a harness program that reads test output and produces
+reports based on it:
+
+ $ prove t/pass.t
+ t/pass....ok
+ All tests successful.
+ Files=1, Tests=1, 0 wallclock secs ( 0.03 cusr + 0.02 csys = 0.05 CPU)
+
+To run all the tests in the F<t> directory recursively use C<prove -r
+t>. This can be put in a F<Makefile> under a I<test> target, for
+example:
+
+ test: Test.php
+ prove -r t
+
+For reference the example test file above looks like this, the shebang
+on the first line is needed so that prove(1) and other test harness
+programs know they're dealing with a PHP file.
+
+ #!/usr/bin/env php
+ <?php
+
+ require 'Test.php';
+
+ plan(1);
+ pass('This dummy test passed');
+ ?>
