  • I was looking at a Slackware package from someone to compare what they had done to package rssowl this way and came across
    to files on in the library /path and the other in /etc

    /etc/gre.conf
    [1.666666]
    GRE_PATH=/usr/lib/mozilla-1.6

    /usr/lib/rssowl-0.73b/logger.dtd
    <!-- DTD used by the java.util.logging.XMLFormatter -->
    <!-- This provides an XML formatted log message. -->

    Of course there is alot more inside logger.dtd, and since I'm new with working on java applications, are these files necessary?
    Thanks
