# Wrapper script for command line tools
#
# Environment Variable Prerequisites
#
#   CATALINA_HOME   May point at your Catalina "build" directory.
#
#   TOOL_OPTS       (Optional) Java runtime options.
#
#   JAVA_HOME       Must point at your Java Development Kit installation.
#                   Using JRE_HOME instead works as well.
#
#   JRE_HOME        Must point at your Java Runtime installation.
#                   Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
#                   are both set, JRE_HOME is used.
#
#   JAVA_OPTS       (Optional) Java runtime options.
#
#   JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories
#                   containing some jars in order to allow replacement of APIs
#                   created outside of the JCP (i.e. DOM and SAX from W3C).
#                   It can also be used to update the XML parser implementation.
#                   This is only supported for Java <= 8.
#                   Defaults to $CATALINA_HOME/endorsed.
