/**
* General purpose wrapper for command line tools that should execute in an
* environment with the common class loader environment set up by Catalina.
* This should be executed from a command line script that conforms to
* the following requirements:
*
* - Passes the
catalina.home system property configured with
* the pathname of the Tomcat installation directory.
* - Sets the system classpath to include
bootstrap.jar and
* $JAVA_HOME/lib/tools.jar.
*
*
* The command line to execute the tool looks like:
*
* java -classpath $CLASSPATH org.apache.catalina.startup.Tool \
* ${options} ${classname} ${arguments}
*
*
* with the following replacement contents:
*
* - ${options} - Command line options for this Tool wrapper.
* The following options are supported:
*
* - -ant : Set the
ant.home system property
* to corresponding to the value of catalina.home
* (useful when your command line tool runs Ant).
* - -common : Add
common/classes and
* common/lib
* - -debug : Enable debugging messages from this wrapper.
* - -server : Add
server/classes and
* server/lib to the class loader repositories.
* - -shared : Add
shared/classes and
* shared/lib to the class loader repositories.
*
* - ${classname} - Fully qualified Java class name of the
* application's main class.
* - ${arguments} - Command line arguments to be passed to
* the application's
main() method.
