=head1 DESCRIPTION
+(By using the L<Test> module, you can write test scripts without
+knowing the exact output this module expects. However, if you need to
+know the specifics, read on!)
+
Perl test scripts print to standard output C<"ok N"> for each single
test, where C<N> is an increasing sequence of integers. The first line
output by a standard test script is C<"1..M"> with C<M> being the
used to let runtests() display the standard output of the script
without altering the behavior otherwise.
+The global variable $Test::Harness::switches is exportable and can be
+used to set perl command line options used for running the test
+script(s). The default value is C<-w>.
+
+If the standard output line contains substring C< # Skip> (with
+variations in spacing and case) after C<ok> or C<ok NUMBER>, it is
+counted as a skipped test. If the whole testscript succeeds, the
+count of skipped tests is included in the generated output.
+
+C<Test::Harness> reports the text after C< # Skip(whatever)> as a
+reason for skipping. Similarly, one can include a similar explanation
+in a C<1..0> line emitted if the test is skipped completely:
+
+ 1..0 # Skipped: no leverage found
+
=head1 EXPORT
C<&runtests> is exported by Test::Harness per default.
=back
+=head1 ENVIRONMENT
+
+Setting C<HARNESS_IGNORE_EXITCODE> makes harness ignore the exit status
+of child processes.
+
+Setting C<HARNESS_NOTTY> to a true value forces it to behave as though
+STDOUT were not a console. You may need to set this if you don't want
+harness to output more frequent progress messages using carriage returns.
+Some consoles may not handle carriage returns properly (which results
+in a somewhat messy output).
+
+Setting C<HARNESS_COMPILE_TEST> to a true value will make harness attempt
+to compile the test using C<perlcc> before running it.
+
+If C<HARNESS_FILELEAK_IN_DIR> is set to the name of a directory, harness
+will check after each test whether new files appeared in that directory,
+and report them as
+
+ LEAKED FILES: scr.tmp 0 my.db
+
+If relative, directory name is with respect to the current directory at
+the moment runtests() was called. Putting absolute path into
+C<HARNESS_FILELEAK_IN_DIR> may give more predicatable results.
+
+The value of C<HARNESS_PERL_SWITCHES> will be prepended to the
+switches used to invoke perl on each test. For example, setting
+C<HARNESS_PERL_SWITCHES> to "-W" will run all tests with all
+warnings enabled.
+
+If C<HARNESS_COLUMNS> is set, then this value will be used for the
+width of the terminal. If it is not set then it will default to
+C<COLUMNS>. If this is not set, it will default to 80. Note that users
+of Bourne-sh based shells will need to C<export COLUMNS> for this
+module to use that variable.
+
+Harness sets C<HARNESS_ACTIVE> before executing the individual tests.
+This allows the tests to determine if they are being executed through the
+harness or by any other means.
