 information, @pxref{G-Expressions}.
 
-Once upon a time, @code{gexp->derivation} did not exist and constructing
-derivations with build code written in Scheme was achieved with
-@code{build-expression->derivation}, documented below.  This procedure
-is now deprecated in favor of the much nicer @code{gexp->derivation}.

-Return a derivation that executes Scheme expression @var{exp} as a
-builder for derivation @var{name}.  @var{inputs} must be a list of
-@code{(name drv-path sub-drv)} tuples; when @var{sub-drv} is omitted,
-@code{"out"} is assumed.  @var{modules} is a list of names of Guile
-modules from the current search path to be copied in the store,
-compiled, and made available in the load path during the execution of
-@var{exp}---e.g., @code{((guix build utils) (guix build
-gnu-build-system))}.
-
-@var{exp} is evaluated in an environment where @code{%outputs} is bound
-to a list of output/path pairs, and where @code{%build-inputs} is bound
-to a list of string/output-path pairs made from @var{inputs}.
-Optionally, @var{env-vars} is a list of string pairs specifying the name
-and value of environment variables visible to the builder.  The builder
-terminates by passing the result of @var{exp} to @code{exit}; thus, when
-@var{exp} returns @code{#f}, the build is considered to have failed.
-
-@var{exp} is built using @var{guile-for-build} (a derivation).  When
-@var{guile-for-build} is omitted or is @code{#f}, the value of the
-@code{%guile-for-build} fluid is used instead.
-
-See the @code{derivation} procedure for the meaning of
-@var{references-graphs}, @var{allowed-references}, @var{local-build?},
-and @var{substitutable?}.
