Summary: Mutt? and Merging a text file with a pdf or postscript file

Thanks for the help...
Here is some of the replies I have recieved.
Please read question two again, I have clarified what I am trying to do.

1.  In Mutt is there away to change the name of the attachment you would
be sending?  Using sendmail I would use the following syntax:
uuecode /tmp/dave.dat  Eng_test.wri | mailx -s "Test Mail" $Mail301

QUESTION 1 Summary
"Thanks Jay Lessert"
The simple-minded way (often the best!) would be:

    ln -s /tmp/dave.dat /tmp/Eng_test.wri
    mutt -a /tmp/Eng_test.wri -s "Test Mail" $Mail301 < /dev/null
    rm tmp/Eng_test.wri

2.  I have been assigned to take a text file and merge it with a pdf or
postscipt file and then send to a printer or email?

I am not sure I was too clear on what I was trying to achieve so I will try
to explain a little more.
We print Invoices on a pre-printed forms on a dot matrix printer.
I would like to create the overlay by scanning it in and saving as a pdf or
PS file,
then taking the text file for the data and overlaying them together.  I
believe
I had stated merging them which most thought of appending to the file.  So
what I wish
to accomplish is having an overlay file and a a text file and putting them
together as one,
then emailing or printing on a laser printer.  This must be done in UNIX
not Adode, since there
will be alot of Invoices printed.  I would like to script it.

QUESTION 2 Summary
I haven't had any answers that will work yet, but I have been pointed at a
few packages that
will do conversions.

a2ps, ghostscript, and PSUtils

Any other suggestion on this issue would be welcome.

Thanks Again to all that have replied to my questions.

Dave
