1) A snowball's got a better chance than convincing all the plugin authors
that they have to invest in Windows Help tools and spend several times as
much time writing the help as they did writing the plugin, and
2) Even if they did, it's about 10 times easier for the plugin to handle
their help as for TCC to do it.
p.s.: 3) Aren't you the guy who's always ranting about how the only
important thing is backwards compatibility? :-)
