[Asterisk-Users] AGI script sample using bash shell script

[Sunny Woo]

Hi,
A quick and dirty (aka Rapid Application Developement) AGI script
implement using bash shell. No need to invoke a 10MB perl engine to
process simple asterisk agi scripts. 

I found it to be very useful in learning the AGI interface. For example,
I learn that AGI won't execute the next command until you read the
results from STDIN. 

Enjoy,
