+## test.php
+
+To run:
+
+    php test.php [flags] [test-name-glob]
+
+
+Runs through all files in `inputs`, compiles them, then compares to respective
+file in `outputs`. If there are any differences then the test will fail.
+
+Add the `-d` flag to show the differences of failed tests.  Defaults to showing
+differences with `diff` but you can set the tool by doing `-d=toolname`.
+
+Pass the `-C` flag to save the output of the inputs to the appropriate file. This
+will overwrite any existing outputs. Use this when you want to save verified
+test results. Combine with a *test-name-glob* to selectively compile.
+
+You can also run specific tests by passing in an argument that contains any
+part of the test name.
+
+## bootstrap.sh
+
+It's a syntetic test comparing lessc and lessphp output compiling twitter bootstrap;
+see bootstrap.sh for details.

+  -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

+  -C              Regenerate ('compile') the reference output files from the

+                           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
