Simple Finger
------------------
I wanted an easy to use finger server that didn't need to expose my IP and stuff to the internet so I wrote this one.

It doesn't expose your user information to the net without a '.singerrc' file placed in your home directory (it automatically detects if you have a weird home directory).

It requires root privileges so it can bind on port 79 (the commonly used finger port).

.singerrc file
-------------------
If the file is not empty, its contents will be sent over to the client.

If it isn't present, the user will be hidden from singer's vision.
