actually i added command line options to the cm app this past weekend,  
including --load, --eval and --batch options.   you can provide  
multiple --eval and --load options, they are processes in a left-to- 
right manner. here is the set i have so far:

hkt$ cm --help
Usage: cm [options]
options:
   --version	print version and exit
   --help	print help and exit
   --load <file>	load file
   --eval <expr>	evaluate expression
   --batch	process options and exit
   --quiet	don't print startup banner

i also completly rewrote the read-loop, it now handles multi-line  
input much better. if you are using the cm console app you should  
definately do a svn update.  i removed the 'q' option for quitting,  
use the (quit) function to quit instead.
