Skribilo.  Additional packages may be found from the ,(ref :url
*skribe-url* :text "Skribe web page"), but they may require slight
modifications to work correctly with Skribilo.])
   
   (p [In order to use the facilities described in the following
sections, the Skribilo source file must contains statements such as:]

(prgm "(use-modules (skribilo package THE-PACKAGE))")

[where ,(tt "THE-PACKAGE") is the desired package.  GNU Guile users will
recognize that this is Guile's standard way to use Scheme modules.  The
effect of the ,(tt [use-modules]) clause is to insert the bindings
exported by ,(tt "THE-PACKAGE") into the current module's name space.
Note that third-party Skribilo packages can have arbitrary Guile module
names.  And of course, the ,(tt [use-modules]) clause can be used to
import ,(emph [any]) Guile module, not just Skribilo packages.])
