+# acov is a tool for gathering coverage information from a device and generating
+# a report from that information. To use:
+#
+# 1. sudo apt-get install lcov
+# 2. Build application/library with coverage information.
+# 3. Push the new binaries to the device.
+# 4. Run tests with the additional environment variables:
+#     * GCOV_PREFIX=/data/local/tmp/gcov
+#     * GCOV_PREFIX_STRIP=`echo $(ANDROID_BUILD_TOP) | grep -o / | wc -l`
+# 5. Run `acov`.
+#
+# acov will pull all coverage information from the device, push it to the right
+# directories, run lcov, and display the coverage report (currently by opening
+# it in your browser).
+#
+
+which lcov
+if [ $? -ne 0 ]; then
