Af alias files contain alias lines and optional blank lines and comment
lines. Comment lines begin with a semicolon (;).
Alias lines look like:
alias:real name:address list
Aliases are case-insensitive non-NULL ASCII character strings,
with any embedded colons preceded by a backslash.
Real names are: double-quoted strings of non-NULL ASCII characters,
with any embedded double-quotes preceded by a backslash;
or, strings of non-NULL ASCII characters, with characters in the
set ( ) < > [ ] @ , . ; : " % preceded by a backslash; or any
combination of the two. In general, the obvious works: consult
the Af Reference Manual for the fine detail in doubtful cases.
Address lists are lists of comma-or-space-separated electronic mail
addresses. For fine detail, consult the Af Reference Manual, and,
if really desperate, RFC 822.
Alias lines may be folded, with a newline followed by a space or TAB
being equivalent to a single space. Folding may only occur after the
alias and its following colon.
EXAMPLE

malc:Mr Author himself:malc
; A mailing list folded over several lines
