should we consider adding gsh to ws and ui? maybe optionally?

Might be useful for people.

Here is an example that works:

if [ "$0" = "" ]; then
arg1=-initEnv
elif [ "$0" = "gsh.sh" ]; then
arg1=-initEnv
else
arg1=$1
if [ "$arg1" = "-initenv" ]; then
arg1=-initEnv
fi
if [ "$arg1" = "-initEnv" ]; then
echo Cannot run gsh.sh -initEnv. Instead use:
echo " source gsh.sh, or"
echo " . gsh.sh"
exit
fi
fi

1. In case something goes wrong
   GROUPER_HOME_SAFE=$GROUPER_HOME

1. Work out where we are
   GROUPER_CUR_DIR=$PWD

1. Guess GROUPER_HOME if not defined
   if [ "$GROUPER_HOME" = "" ]; then
   if [ "$arg1" = "-initEnv" ]; then
   echo Attempting to reset GROUPER_HOME
   fi
   #:noGrouperHome
   GROUPER_HOME=$GROUPER_CUR_DIR
   fi

#:checkGrouperHome
if [ -f "$GROUPER_HOME/bin/gsh.sh" ]; then
GROUPER_DUMMY=
else

1. In case we are in 'bin' try teh parent directory
   GROUPER_HOME=$GROUPER_CUR_DIR/..
   fi

#:gotHome
if [ -f "$GROUPER_HOME/bin/gsh.sh" ]; then
GROUPER_DUMMY=
else

1. Bad GROUPER_HOME
   if [ "$arg1" = "-initEnv" ]; then
2. Something isn't right so revert to whatever we started with
   GROUPER_HOME=$GROUPER_HOME_SAFE
   fi
   #:badGrouperHome
   echo The GROUPER_HOME environment variable is not defined correctly
   echo or could not be determined
   echo This script must be located in "<GROUPER_HOME>" or "<GROUPER_HOME>/bin"
   exit
   fi

#:okHome

PATH="$GROUPER_HOME/bin:$PATH"
if [ "$arg1" = "-initEnv" ]; then
echo Added $GROUPER_HOME/bin to PATH
echo Setting GROUPER_HOME=$GROUPER_HOME
export GROUPER_HOME
fi

if [ "$2" != "" ]; then
if [ -f "$2/grouper.properties" ]; then
GROUPER_CONF=$2
echo Using GROUPER_CONF=$GROUPER_CONF
fi
fi

#:run

1. We aren't initing so handle args

1. Get standard environment variables
   if [ -f "$GROUPER_HOME/bin/setenv.sh" ]; then
   . "$GROUPER_HOME/bin/setenv.sh"
   fi

if [ "$MEM_START" = "" ];then
MEM_START=64m
fi

if [ "$MEM_MAX" = "" ]; then
MEM_MAX=512m
fi

if [ "$GROUPER_CONF" = "" ]; then
GROUPER_CONF=$GROUPER_HOME/classes
fi

JAVA=java

if [ -n "$JAVA_HOME" ]; then
JAVA="$JAVA_HOME/bin/java"
fi

if [ "$arg1" != "-initEnv" ]; then

1. ----- Execute The Requested Command ---------------------------------------

echo Using GROUPER_HOME: $GROUPER_HOME
echo Using GROUPER_CONF: $GROUPER_CONF
echo Using JAVA: $JAVA
echo using MEMORY: $MEM_START-$MEM_MAX
