-Usage: $0 [-r]
-Collect coverage statistics of library code into an HTML report.
-
-General instructions:
-1. Build the library with CFLAGS="--coverage -O0 -g3" and link the test
-   programs with LDFLAGS="--coverage".
-   This can be an out-of-tree build.
-   For example (in-tree):
-        make CFLAGS="--coverage -O0 -g3" LDFLAGS="--coverage"
-   Or (out-of-tree):
-        mkdir build-coverage && cd build-coverage &&
-        cmake -D CMAKE_BUILD_TYPE=Coverage .. && make
-2. Run whatever tests you want.
-3. Run this script from the parent of the directory containing the library
-   object files and coverage statistics files.
-4. Browse the coverage report in Coverage/index.html.
-5. After rework, run "$0 -r", then re-test and run "$0" to get a fresh report.
-
-Options
-  -r    Reset traces. Run this before re-testing to get fresh measurements.
