* Use the output from "uname -s" to auto-select the target in the Makefile.
* Write more ./READMEs/README.* files
* Implement more test programs in ./testdir
* Long and short command options.
* Implement a config file (/etc/identd.conf).
* Implement some way for an external program to register indirect
pointers. For example a TCP/IP relaying daemon might wanna do this.
So that the <Identifier> returned will look something like:
42 , 4711 : USERID : OTHER : foo (fubar.su!bar)
or:
42 , 4711 : USERID : OTHER : foo (this.host.se!foo (fubar.su!bar))
Probably should be implemented using a UNIX domain socket with access
control.
* Implement some way to encrypt <Identifiers>.
