How do I automate mutt in a script?

[Gerald Manipon]

I am writing a script which uses mutt to create an email with an attachment
with
"mutt -a atfile.doc -s subject [EMAIL PROTECTED]".  But it always brings up the
vi screen
to enter the message for my body.  Is there a way for me to create text
files with
default message bodies, and use the mutt command to automatically compose an
email
without prompting me for any input?  Any help will be appreciated.
