searchable reference

Hello everyone,

I have started using scsh for scripting and experiments and was
wondering if there was such a thing.  I have been spoiled by plt's
help-desk, and was wondering if there was something like a searchable
form of the various documents, ie. R5RS, srfis?  I have cheat.txt for
scsh specific stuff, but it would be nice to be able to refer to these
other aspects of scheme.

Any ideas would be most appreciated, and speed my absorbtion into scsh
considerably.

Thanks,

rohan
