+# This script creates a patched FFmpeg tree suitable for using to build
+# the FFmpeg needed by chromium.  It takes an |output_dir| where the
+# final source tree will reside, and |patches_dir| containing patches
+# to apply to the pristine source.
+#
+# The pristine source is contained in:
+#
+#   ffmpeg-mt.tar.gz
+#
+# After unpacking these files into the |output_dir|, all files inside
+# the directory tree at |patch_dir| matching the pattern *.patch will be
+# applied to the output directory in lexicographic order.
