# Find kscript directory ($KSCRIPT_HOME).
# On linux (and cygwin) "KSCRIPT_HOME=$(basedir $(readlink -f $0))" works,
# but Macos' readlink is very different.
# This works on linux, cygwin, and macos:
KSCRIPT_HOME=$(cd -P -- "$(dirname -- "$0")" && pwd -P) && KSCRIPT_HOME=$KSCRIPT_HOME/$(basename -- "$0")

## resolve application jar path from script location and convert to windows path when using cygwin
jarPath=$(dirname $0)/kscript.jar
## resolve application jar path from $KSCRIPT_HOME and convert to windows path when using cygwin
jarPath="${KSCRIPT_HOME}/kscript.jar"
if [[ $(uname) == CYGWIN* ]]; then jarPath=$(cygpath -w ${jarPath}); fi

## run it using command substitution to have just the user process once kscript is done
