  Add some examples.
  
  Revision  Changes    Path
  1.1                  jakarta-commons-sandbox/daemon/src/samples/README.txt
  
  Index: README.txt
  ===================================================================
  The directory contains examples of java daemons.
  The examples are compiled using ant (just type ant). Each example creates a
  jar file in ../../dist
  
  SimpleDaemon:
  
  SimpleDaemon demonstrates the feature of the daemon ofered by
  jakarta-commons-sandbox/daemon.
  To run it adapt the SimpleDaemon.sh file and connect to it using:
  telnet localhost 1200
  Additional information in ../native/unix/INSTALL.txt
  
  ServiceDaemon:
  
  ServiceDaemon allows to start programs using the jakarta daemon.
  That could be usefull when using cygwin under win9x because cygwin only offers
  services support under win NT/2000/XP.
  (See in ../native/nt/README how to install jsvc as a service in win32).
  
  It uses jakarta Commons Collections:
  http://jakarta.apache.org/commons/collections.html
  To use it you need at least commons-collections-1.0
  
  You have to create a file named startfile that uses a property format:
  name = string to start the program
  
  For example:
  sshd /usr/sbin/sshd -D
  router1 /home/Standard/router/router pop3 pop3.example.net
  router2 /home/Standard/router/smtp smtp.example.net
  socks5  /usr/local/bin/socks5 -f
  
  To run it adapt the ServiceDaemon.sh file.
