I am about use libexpect directly in C/C++, and have some related
questions by far:

1,  Where can I get support about libexpect? Is there a mailing for
it?
2,  libexpect man page methioned 'compiled regular expression, but how
can I get a 'compiled regular expression'?
3,  The man page descripted how to read/expect spawned process's
outputs, but it did not mention how to send data to the process
( expect's send command ).  Does that imply I should always write(2)
to the spawned file descriptor when I need to?

Thanks in advance.
