+# Compiles the Javascript implementation of libphonenumber, using the Google

+#
+# The environment variable CLASSPATH is used to provide the location of the
+# Closure Compiler JAR (compiler.jar), and the environment variable CLOSUREPATH
+# is used to provide the root directory of the Closure library source files. If
+# the defaults don't work for your system, override them on the command line,
+# for example like this:
+#
+# CLASSPATH=/opt/closure-compiler/compiler.jar ./compile.sh
+
+: ${CLASSPATH:='/usr/local/share/closure-compiler/compiler.jar'}
+: ${CLOSUREPATH:='../../closure-library/closure/goog'}
+
+# If CLASSPATH was set by this script, it needs to be exported to make it
+# visible to the JVM.
