+/**
+ * This class finds a UNO installation on the system.
+ *
+ * <p>A UNO installation can be specified by the user by either setting the
+ * com.sun.star.lib.loader.unopath system property or by setting the
+ * UNO_PATH environment variable to the program directory of a UNO
+ * installation.
+ * Note, that Java 1.3.1 and Java 1.4 don't support environment variables
+ * (System.getenv() throws java.lang.Error) and therefore setting the UNO_PATH
+ * environment variable won't work with those Java versions.
+ * If no UNO installation is specified by the user, the default installation
+ * on the system will be returned.</p>
+ *
+ * <p>On the Windows platform the default installation is read from the Windows
+ * Registry.</p>
+ *
+ * <p>On the Unix/Linux platforms the default installation is found from the
+ * PATH environment variable. Note, that for Java 1.3.1 and Java 1.4 the
+ * default installation is found by using the 'which' command, because
+ * environment variables are not supported with those Java versions.
+ * Both methods require that the 'soffice' executable or a symbolic
+ * link is in one of the directories listed in the PATH environment variable.
+ * For older versions than OOo 2.0 the above described methods may fail.
+ * In this case the default installation is taken from the .versionrc file in
+ * the user's home directory. Note, that the .sversionrc file will be omitted
+ * for OOo 2.0</p>
