17# acov is a tool for gathering coverage information from a device and generating
18# a report from that information. To use:
19#
20# 1. sudo apt-get install lcov
21# 2. Build application/library with coverage information.
22# 3. Push the new binaries to the device.
23# 4. Run tests with the additional environment variables:
24#     * GCOV_PREFIX=/data/local/tmp/gcov
25#     * GCOV_PREFIX_STRIP=`echo $(ANDROID_BUILD_TOP) | grep -o / | wc -l`
26# 5. Run `acov`.
27#
28# acov will pull all coverage information from the device, push it to the right
29# directories, run lcov, and display the coverage report (currently by opening
30# it in your browser).
