## Save the current PATH only once in OLD_PATH_VAR and use OLD_PATH_VAR
## instead of PATH for the first PATH extension. If you extend the PATH
## environment variable _after_ you have executed setvars, the next
## "setvars" invocation will overwrite these additions with OLD_PATH_VAR.
## Similar remarks with respect to CLASSPATH. Saving PATH and CLASSPATH
## the first time allows you to invoke file "setvars" several times
## without leaving the current shell :

if [ -z "$OLD_PATH_VAR" ]
then
	OLD_PATH_VAR=$PATH
	export OLD_PATH_VAR
fi

if [ -z "$OLD_CLASSPATH_VAR" ]
then
	OLD_CLASSPATH_VAR=$CLASSPATH
	export OLD_CLASSPATH_VAR
fi

## DLP_ROOT=<YOUR_PATH>/dlp1r22
## or (to run the Solaris examples) :

DLP_ROOT=/home/dejavu/dlp/dlp1r22
export DLP_ROOT

## dlp, dlpc commands :
PATH=$DLP_ROOT/bin:$OLD_PATH_VAR	# first PATH

## remove the next "jikes" lines in case you prefer
## SUN's javac compiler for compiling Java programs:
## The jikes executable is in directory :
JIKES_EXEC=/home/dejavu/jikes-1.06	## or ..../bin
export JIKES_EXEC

PATH=$JIKES_EXEC:$PATH

## SWI-Prolog executable in :
SWI_EXEC=/home/dejavu/pl/pl-3.3.10/bin
export SWI_EXEC

PATH=$SWI_EXEC:$PATH

## where to find java, javac, etc. :
JAVA_ROOT=/usr/local/java/jdk1.2.2
export JAVA_ROOT

PATH=$JAVA_ROOT/bin:$PATH

export PATH

## next 3 lines are only required for special purpose Java
## interpreters (or "oldjava") that use the Java 1.X.Y
## libraries and the jikes compiler :
CLASSPATH=$JAVA_ROOT/src.jar:$OLD_CLASSPATH_VAR	# first CLASSPATH
CLASSPATH=$JAVA_ROOT/jre/lib/i18n.jar:$CLASSPATH
CLASSPATH=$JAVA_ROOT/jre/lib/rt.jar:$CLASSPATH

## (Precompiled) DLP + examples class files:
# CLASSPATH=$DLP_ROOT/classes:$CLASSPATH
CLASSPATH=$DLP_ROOT/classes/dlpsys.jar:$CLASSPATH

## to run the examples:
# CLASSPATH=$DLP_ROOT/examples/classes:$CLASSPATH

## In case you would like to write and compile DLP programs in
## directory MY_PROG_DIR, remove the # comment character
## and adjust one of the following lines :

# CLASSPATH=MY_PROG_DIR/classes:$CLASSPATH
## or, e.g. :
CLASSPATH=`pwd`/classes:$CLASSPATH

export CLASSPATH

## classes for jikes:
JIKESPATH=$CLASSPATH
export JIKESPATH

echo DLP_ROOT $DLP_ROOT
echo CLASSPATH $CLASSPATH
