+This script is used to generate Windows resources file for the FFmpeg libraries.
+The output .rc file is to be compiled by windres(1). It is mainly useful for
+FFmpeg developers to tweak and regenerate all resources files at once.
+
+Usage: $0 <libname> <comment>
+
+The script will output the file to '<libname>/<libname-without-lib>res.rc'.
+
+Example: $0 libavcodec 'FFmpeg codecs library'
+EOF
+    exit 1
+}
+
+# Script to generate all:
+# (to remove prefix '# ' and add 'tools/' as prefix: sed -r 's/^.{2}/tools\//')
+# gen-rc libavutil     "FFmpeg utility library"
+# gen-rc libavcodec    "FFmpeg codec library"
+# gen-rc libavformat   "FFmpeg container format library"
+# gen-rc libavdevice   "FFmpeg device handling library"
+# gen-rc libavfilter   "FFmpeg audio/video filtering library"
+# gen-rc libpostproc   "FFmpeg postprocessing library"
+# gen-rc libavresample "Libav audio resampling library"
+# gen-rc libswscale    "FFmpeg image rescaling library"
+# gen-rc libswresample "FFmpeg audio resampling library"
