+# m
+
+`m` stands :metal: (metal), which is a better test/unit test runner. @sferik took `t` so this was the next best option.
+
+## Usage
+
+Basically, I was sick of using the `-n` flag to grab one test to run, like RSpec's test runner works.
+
+Given this file:
+
+     $ cat -n test/example_test.rb
+     1	require 'test/unit'
+     2	
+     3	class ExampleTest < Test::Unit::TestCase
+     4	  def test_apple
+     5	    assert_equal 1, 1
+     6	  end
+     7	
+     8	  def test_banana
+     9	    assert_equal 1, 1
+    10	  end
+    11	end
+
+You can run a test by line number, using format `m TEST_FILE:LINE_NUMBER_OF_TEST`:
+
+    $ m test/example_test.rb:4
+    Run options: -n /test_apple/
+
+    # Running tests:
+
+    .
+
+    Finished tests in 0.000525s, 1904.7619 tests/s, 1904.7619 assertions/s.
+
+    1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
