+################### coverage
+# A target that creates a visual representation of which files and
+# lines are covered by the testsuite, the example programs, and
+# possible other executables. To use this rule, configure deal.II
+# as usual, then add "-fprofile-arcs -ftest-coverage" to the following
+# variables in common/Make.global_options:
+# - SHLIBFLAGS
+# - LDFLAGS
+# - CXXFLAGS.g
+# Then compile the library and run all the executables for which you
+# want it reported that. Note, however, that you can't run them in
+# parallel or they will step on each other's toes when writing output.
+# In other words, the testsuite has to be run with -j1, however long
+# that may take.
+#
+# When all of these programs have been run, the do
+#   cd source
+#   make coverage
+# This may take a long time: both running lcov and, in particular,
+# genhtml can take hours. In the latter case, there isn't even an
+# indication that anything is happening, but it is -- just be
+# patient, let it run overnight.
