Make sure you have a suitable version of Java instlled

java -version

You need version 1.5 or greater.

Run the download manager

For exampleFrom the directory where you save netx-0.5.jar issue the following command.

java -jar netx-0.5.jar -verbose -headless -basedir ~/.downloadManager -jnlp http://glast-ground.slac.stanford.edu/DownloadManager/LineMode.jnlp -arg --folder=/Data/Flight/Level1/LPA -arg --group=FT1 

Notes:

• We need a front-end script to make the command simpler
• We need to document the options
• The format of the downloaded files will change shortly
• The download manager checks if the files to be downloaded already exist. If so they will not be downloaded again. If a newer version exists it will replace the existing version (and the existing version will be renamed *-old-n)
