+Usage: ./test.php [options] [searchstring]

+
+  -d=[difftool]   Show the diff of the actual output vs. the reference when a
+                  test fails; uses 'diff -b -B -t -u' by default.
+
+                  The test is aborted after the first failure report, unless
+                  you also specify the '-g' option ('go on').
+
+  -g              Continue executing the other tests when a test fails and
+                  option '-d' is active.
+
+  -C              Regenerate ('compile') the reference output files from the
+                  given inputs.
+
+                  WARNING: ONLY USE THIS OPTION WHEN YOU HAVE ASCERTAINED
+                           THAT lessphp PROCESSES ALL TESTS CORRECTLY!
+
+The optional [searchstring] is used to filter the input files: only tests
+which have filename(s) containing the specified searchstring will be
+executed. I.e. the corresponding glob pattern is '*[searchstring]*.less'.
+
+The script EXIT CODE is the number of failed tests (with a maximum of 255),
+0 on success and 1 when this help message is shown. This aids in integrating
+this script in larger (user defined) shell test scripts.
+
+
+Examples of use:
+
+- Test the full test set:
+    ./test.php
+
+- Run only the mixin tests:
+    ./test.php mixin
+
+- Use a custom diff tool to show diffs for failing tests
+    ./test.php -d=meld
