1 Reserved plugin letters
2 -----------------------
4 Used in @x24R@ constructs where x is:
7 M - Mark 'n lard plugin.
8 S - Sesame Street plugin.
15 Used in @x constructs where x is:
17 B - Newline (think Break line)
21 V - Version in the form x.y.z
23 @NOTAG@ is special and means that no tagline is to be appended to this sig
24 but that it will still be parsed and have macros substituted etc.
26 The name variants are only available if htag is passed a message with
27 headers like "To: Simon Huggins <huggie@earth.li>".
33 This isn't supported yet but I think it's what I want. I just need to be
34 able to match nested constructs but I think there is a module for this.
36 Used in @x24@ constructs where x is:
38 CENTER - Center over line width
40 LEFT - Left align with padding
42 Without a following length the operations are done over the line width.
