## Help
die() {
    cat <<EOF >&2
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"

## Sanity checks and argument parsing
if test $# -lt 2 || test $# -gt 3; then
    die
fi

name=$1
shortname=${name#lib}
comment=$2
capname=`echo $name | awk '{print toupper($0)}'`
version=${capname}_VERSION

mkdir -p "$name"
output="$name/${shortname}res.rc"

## REAL magic
cat <<EOF > $output
