Maybe there shouldn't be a separate attach man page, but that doesn't seem like 
compelling reason, It just says that it shouldn't be in man/man1 but possibly
man/man7, See man 7 intro.

Instead of saying what information should be in what man pages, and what man
pages should exist, let me opine a desideratum:

Granted that what goes on under the hood (relationship of attach to send etc.)
needs documentation, there ought to be documentation for the user-clod like me,
who sees the attach facility as a separate entity. It should include such things
as: (these are examples)

     The syntax of attach: multiple files, escapes etc. (David, isn't this
     already more than one paragraph?)

     Recipients will only see base names of the arguments to attach

     Extension names are case insensitive.

     What happens if a file has an unrecognized extension


All of this might be obvious to you, but it wasn't to me. And a lot of it
probably still isn't.

Lest my griping mask my pleasure with the attach facility, let me make it clear
that I'm delighted by it.

Very naive, stupid question: Why wasn't attach implemented as a shell level
command. Don't need to know, just curious.
