package com.sun.servicetag;

// This class is a copy of the com.sun.scn.servicetags.SolarisSystemEnvironment
// class from the Sun Connection source.
//
// The Service Tags team maintains the latest version of the implementation
// for system environment data collection.  JDK will include a copy of
// the most recent released version for a JDK release. We rename
// the package to com.sun.servicetag so that the Sun Connection
// product always uses the latest version from the com.sun.scn.servicetags
// package. JDK and users of the com.sun.servicetag API
// (e.g. NetBeans and SunStudio) will use the version in JDK.
//
// So we keep this class in src/share/classes instead of src/<os>/classes.
