Auto close Extension Manager from Command Line?

Question

I'm putting together a simple shell script to build a tool so that our Continuous Integraion system can build this tool.  The scirpt works but I can't figure out how to close Extension Manager once the job is done...
Shell Script:
#!/usr/bin/env bash
app="/Applications/Adobe/Adobe Extension Manager CS5.5/Adobe Extension Manager CS5.5.app/Contents/MacOS/Adobe Extension Manager CS5.5"
filename=MyToolsName
srcMxiPath="$filename.mxi"
outMxpPath="$PWD/$filename".mxp
echo "Outputting Adobe Extention Here: $outMxpPath"
"$app" -package mxi="$srcMxiPath" mxp="$outMxpPath" timeout=30

Answer 1

I needed to add:
-suppress
Here is the completed script:
#!/usr/bin/env bash
app="/Applications/Adobe/Adobe Extension Manager CS5.5/Adobe Extension Manager CS5.5.app/Contents/MacOS/Adobe Extension Manager CS5.5"
filename=MyToolsName
srcMxiPath="$filename.mxi"
outMxpPath="$PWD/$filename".mxp
if [ -f $outMxpPath ]; then
          echo Deleting old MXP.
          rm $outMxpPath
fi
echo "Outputting Adobe Extention Here: $outMxpPath"
"$app" -suppress -package mxi="$srcMxiPath" mxp="$outMxpPath"
