/*
NAME
strin - test whether mu_strin is functioning.
DESCRIPTION
This test program reads data from mu_strin and prints it on stdout
using stdio function call.
The mu_strin object, as well as the other two standard streams, springs
into existence the first time it is used by any function of the stream
family. Therefore, care is taken not to call any mailutils I/O function
either directly or indirectly prior to the first read from mu_strin.
OPTIONS
-noecho
If mu_strin is attached to a tty, this option disables echoing of
the data read.
