To Eamonn: I can't reach you or what?! Could you send me a UUCP bang path?
Enjoy.

X
X+ Substitute replacement patterns.
X+
X+ The basic metacharacters for the replacement pattern are `&' and `~'; these
X+ are given as `\&' and `\~' when nomagic is set. Each instance of `&' is
X+ replaced by the characters which the regular expression matched. The meta-
X+ character `~' stands, in the replacement pattern, for the defining text of
X+ the previous replacement pattern.
X+ Other metasequences possible in the replacement pattern are always introduced
X+ by the escaping character `\'. The sequence `\n' (with `n' in [1-9]) is
X+ replaced by the text matched by the n-th regular subexpression enclosed between
X+ `\(' and `\)'. The sequences `\u' and `\l' cause the immediately following
X+ character in the replacement to be converted to upper- or lower-case
X+ respectively if this character is a letter. The sequences `\U' and `\L' turn
X+ such conversion on, either until `\E' or `\e' is encountered, or until the end
X+ of the replacement pattern.
