Jigsaw env. vars. on Linux..

Hi,

	I noticed that in the file <Jigsaw_Home>/scripts/jigsaw.sh the
CLASSPATH and LD_LIBRARY_PATH variables are being set and exported. This
might override the $CLASSPATH setup by the user earlier. Hence they might
have to be changed include the pre-existing env. vars.

LD_LIBRARY_PATH=${JIGSAW_HOME}/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH

CLASSPATH=${JIGSAW_HOME}/classes/jigsaw.zip:${JIGSAW_HOME}/classes/servlet.jar:.:${CLASSPATH}
export CLASSPATH

	This was actually causing me an error when I was accessing class
files located in other directories.

Thanks,
Bharat
