-Compile qinit_srv.c to qinit_srv as usual
-Compile your applications at shared libraries instead of as executables:
-    eg: gcc test.c -o test.so -shared
-Make a symbolic link from qinit_srv to the name of the application:
-    eg: ln -s qinit_srv test
-Now make sure 'test' (The symlink) and 'test.so' (the shared library version of the app) are together.
-When you run ./test it will load test.so and run it just like you were running the application for real.
-There will be a qinit_srv process created the first time you run a program this way.
-
-How it works:
-
-qinit_srv checks to see if there is already a server, if not it starts as a server which runs in the background as a deamon.
-If it's a server it loads all the libraries listed in the library.lst file.
-It then waits for signals to be sent to it which tell it to fork itself and load shared libraries and run them.
-If it decides it's not the server, it sends a signal to the server to run the given command.
-The server then executes a shared object file of whatever name the original process is invoked as (argv[0], the symlink trick)
-The other process waits until the forked server finishes and signals the original process that it as finished and to return
