Hi,

This is a C version of the Perl 'hey' program used here and there. It's nice.
To install it, the usual 

./configure
make
make install

This will install the c-hey binary and manpage into the default prefix (/usr/local/)
and create symlinks to each as hey and hey.1

That should do the trick. Let me know if you have to change anything to get it 
working on any system. 

Quick tour:
-----------
aux.c, .h               - Some support functions
dyn_page.c, .h          - A general-use growable buffer
g_list.c, .h            - A general-use list object
hey_arg.c, .h           - Parse the cmdline arguments & environment variables
hey_format.c, .h        - Read in & format user input 
hey_logins.c, .h        - Check if a user is logged in/exists etc.
hey_main.c              - The business end
hey_signal.c, .h        - Handle/ignore signals & terminal settings
utent.c, .h             - Replacement *ut* functions for systems lacking them
hey_readline.c, .h	- libreadline independent hooks for readling lines
hey_edit.c, .h		- libreadline dependent screen handling, for multi-line editing

Mail c-hey@redbrick.dcu.ie any improvements you can make to the code, or any 
suggestions & questions (feel free to ask about parts that are unclear) ...
Thanks, 

Cian <pooka@redbrick.dcu.ie>
