+bats(1) -- Bash Automated Testing System
+========================================
+
+SYNOPSIS
+--------
+
+bats [-c] [-p | -t] <test> [<test> ...]
+
+
+DESCRIPTION
+-----------
+
+
+Bats is a TAP-compliant testing framework for Bash.
+It provides a simple way to verify that the UNIX programs you write behave as expected.
+
+Bats is most useful when testing software written in Bash, but you can use it to test any UNIX program.
+
+
+FILES
+-----
+
+To run your tests, invoke the `bats` interpreter with a path to a test
+file. The file's test cases are run sequentially and in isolation. If
+all the test cases pass, `bats` exits with a `0` status code. If there
+are any failures, `bats` exits with a `1` status code.
+
+You can invoke the `bats` interpreter with multiple test file
+arguments, or with a path to a directory containing multiple `.bats`
+files. Bats will run each test file individually and aggregate the
+results. If any test case fails, `bats` exits with a `1` status code.
+
+
+OPTIONS
+-------
+
+  * `-c`, `--count`:
+    Count the number of test cases without running any tests
+  * `-h`, `--help`:
+    Display this help message
+  * `-p`, `--pretty`:
+    Show results in pretty format (default for terminals)
+  * `-t`, `--tap`:
+    Show results in TAP format
+  * `-v`, `--version`:
+    Display the version number
+
+    
+EXAMPLES
+--------
+
+
+When you run Bats from a terminal, you'll see output as each test is
+performed, with a check-mark next to the test's name if it passes or
+an "X" if it fails.
+
+    $ bats addition.bats
+     ✓ addition using bc
+     ✓ addition using dc
+
+    2 tests, 0 failures
+
+If Bats is not connected to a terminal—in other words, if you
+run it from a continuous integration system or redirect its output to
+a file—the results are displayed in human-readable, machine-parsable
+[TAP format](http://testanything.org/wiki/index.php/TAP_specification#THE_TAP_FORMAT).
+You can force TAP output from a terminal by invoking Bats with the
+`--tap` option.
