-OpenJDK 6 is an open source implementation of version 6 of the Java
-Development Kit, Standard Edition. It includes tools for developing,
-testing, and running programs written in Java.
-
-apache-ant is a required dependency and you have to install it before
-you build openjdk6. However, you do not need to install Oracle's jdk,
-since it's only a runtime dependency of apache-ant.
-
-Before installing this package please consider any other jdk's/jre's
-that you have already installed as they may cause conflicts with the
-PATH, JAVA_HOME and MANPATH variables.
-
-After installing the package you will need to logout/reboot your
-machine as it will add new files to the /etc/profile.d folder.
-
-This script may take a couple of hours to complete and will require
-about 11 GB of disk space for its temporary directory. It defaults to
-"/tmp/SBo" and you may redefine it like this:
-
-TMP=/your/temporary/dir ./openjdk6.SlackBuild
-
-The 'cacerts' binary is a keystore containing CA certificates which
-are used by Java applications. It is taken from the CentOS package
-'ca-certificates-2015.2.4-65.0.1.el6_6.noarch.rpm'.
-
-If you get an error like
-
-Internal compiler error: java.lang.NullPointerException at
-org.eclipse.jdt.internal.compiler.ReadManager.run(ReadManager.java:166)
-
-simply run the build again. This happens early so it shouldn't be that
-of a problem. At least 1 out of 5 runs so far have always succeded.

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.
-# Line up the first '|' above the ':' following the base package name, and
-# the '|' on the right side marks the last column you can put a character in.
-# You must make exactly 11 lines for the formatting to be correct.  It's also
-# customary to leave one space after the ':' except on otherwise blank lines.
