+# This script copies log files from a GCC build directory, compresses
+# and indexes them for web browser access.  It's aimed at having an
+# easy-to-access collection of files for analyzing regressions without
+# needing to run the build yourself.  Binary files (.o, executables)
+# are intentionally not included since usually if they are needed it's
+# better to just run a build, and because they take up a lot of space.
+
+# 'srcdir' is the root directory of a GCC build (was $objdir in the build).
+# 'destdir' will be erased and replaced with the log files, and should be an
+#   absolute path.
+# 'branchname' is used only to produce the title of the index page,
+#   which will be named 'index.html'.
