@end defvr
@defvr {Scheme Variable} chicken-build-system
This variable is exported by @code{(guix build-system chicken)}.
It builds Chicken Scheme modules (also called ``eggs'' or ``extensions'').
Chicken generates C source code, which then gets compiled by a C compiler,
in this case GCC.
It adds @code{chicken} to the package inputs, as well as the packages of
@code{gnu-build-system}.
The build system can't (yet) deduce the egg's name automatically, so just like
with @code{go-build-system} and its @code{#:import-path}, you should define
@code{#:egg-name} in the package's @code{arguments} field.
For example, if you are packaging the srfi-1 egg:
@lisp
(arguments '(#:egg-name "srfi-1"))
@end lisp
Egg dependencies must be defined in @code{propagated-inputs}, not @code{inputs}
because Chicken doesn't embed absolute references in compiled eggs.
Test dependecies should go to @code{native-inputs}, as usual.
@end defvr
@defvr {Scheme Variable} copy-build-system
