finding procedure definitions

[Scott N. Walck]

Guile folks,

Is there a way to ask for the definition of a procedure or to find the
source code for a procedure?

For example, "symbol" is a guile procedure.  I can see that by typing
its name.

guile> symbol
#<procedure symbol args>

But how can I find more information, such as its definition, including
what types of arguments it expects and what it does and returns?  I
don't see symbol listed in the Guile Reference manual index.  I'm not
sure where to look in the source code.

Thanks,

Scott
