INSTALL - quick and dirty install instructions

To install, first run configure.pl:

[jon@chainik ~/signature]$ ./configure.pl

Answer the questions it asks, and it will create the Makefile.  Next build
and install the program.

[jon@chainik ~/signature]$ make
...
[jon@chainik ~/signature]$ su
Password:
[root@chainik ~jon/signature]# make install
...
[root@chainik ~jon/signature]# exit
[jon@chainik ~/signature]$

Then, you need merely start signature, and you will have a working
signature pipe.
