FILE=$1
if [ ! -f "${FILE}" ]; then
echo "Input file '${FILE}' missing, exiting."
exit 1
fi

# safety check 2
JAD="${FILE%.*}.jad"
if [ -f "${JAD}" ]; then
echo "${JAD} already exists, overwrite? (y/N)"
read tmpans
answer=$(echo "$tmpans" | tr '[:upper:]' '[:lower:]')
if [ "$answer" != "y" ] && [ "$answer" != "yes" ]; then

# unzip the internal manifest, changing line endings to our local OS
# the sed action removes blank lines, with or without spaces/tabs
unzip -aa -j -p ${FILE} "META-INF/MANIFEST.MF" | sed -e '/^[ \t]*$/d' > "${JAD}"

# generic variables
echo "MIDlet-Jar-URL: ${FILE}" >> "${JAD}"
echo "MIDlet-Info-URL: http://" >> "${JAD}"

# actual jarball size
FILESIZE=$(stat -c%s "${FILE}")
echo "MIDlet-Jar-Size: ${FILESIZE}" >> "${JAD}"

# weee
echo "Created ${JAD}."
exit 0
