+Apache Ant is a Java-based build tool - like make, but without make's
+wrinkles. :-)
+
+Ant is extended using Java classes. The configuration files are XML-based,
+calling out a target tree where tasks get executed. Each task is run by an
+object that implements a Task interface.
+
+apache-ant uses `javac` and friends to compile java projects.
+
+This apache-ant199 package can be installed alongside any newer apache-ant
+package made available as a SlackBuild.
+
+Still having apache-ant version 1.9.9 available can be helpful in cases
+when newer apache-ant versions throw Exceptions about an "unrecognized class
+file version" - e.g.:
+
+Exception in thread "main" java.lang.ClassFormatError: org.apache.tools.ant.laun
+ch.Launcher (unrecognized class file version)
+   at java.lang.VMClassLoader.defineClass(libgcj.so.16)
+   at java.lang.ClassLoader.defineClass(libgcj.so.16)
+   at java.security.SecureClassLoader.defineClass(libgcj.so.16)
+   at java.net.URLClassLoader.findClass(libgcj.so.16)
+   at java.lang.ClassLoader.loadClass(libgcj.so.16)
+   at java.lang.ClassLoader.loadClass(libgcj.so.16)
+   at gnu.java.lang.MainThread.run(libgcj.so.16)
+
+How to use this apache-ant199 build tool instead of whichever version was
+installed by the default apache-ant SlackBuild package?
+Simple:
+In your console or terminal, you 'source' the provided profile script,
+like this (a c-shell compatible script is available as well):
+
+  source /etc/profile.d/apache-ant199.sh
+
+The command 'source' is equivalent to the dot command ' . '.
+The profile script will (re-)define the common variables that are used
+by make and other programs to determine which Apache Ant binary to run:
+
+export ANT_HOME=/usr/share/ant199
+PATH=${ANT_HOME}/bin:${PATH}
+
+Nothing else needs to be done after sourcing the profile script.
+All you do next is run your apache-ant job as usual in that same console.
