fixed-output derivation is created---i.e., one whose result is known in
advance, such as a file download. If, in addition, RECURSIVE? is true, then
that fixed output may be an executable file or a directory and HASH must be
the hash of an archive containing this output.
When REFERENCES-GRAPHS is true, it must be a list of file name/store path
pairs. In that case, the reference graph of each store path is exported in
the build environment in the corresponding file, in a simple text format.
When ALLOWED-REFERENCES is true, it must be a list of store items or outputs
that the derivation's outputs may refer to. Likewise, DISALLOWED-REFERENCES,
if true, must be a list of things the outputs may not refer to.
When LEAKED-ENV-VARS is true, it must be a list of strings denoting
environment variables that are allowed to \"leak\" from the daemon's
environment to the build environment. This is only applicable to fixed-output
derivations--i.e., when HASH is true. The main use is to allow variables such
as \"http_proxy\" to be passed to derivations that download files.
When LOCAL-BUILD? is true, declare that the derivation is not a good candidate
for offloading and should rather be built locally. This is the case for small
derivations where the costs of data transfers would outweigh the benefits.
When SUBSTITUTABLE? is false, declare that substitutes of the derivation's
output should not be used."

tuples; when SUB-DRV is omitted, \"out\" is assumed. 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

EXP is evaluated in an environment where %OUTPUT is bound to the main

%BUILD-INPUTS is bound to an alist of string/output-path pairs made from

name and value of environment variables visible to the builder. The
builder terminates by passing the result of EXP to `exit'; thus, when
EXP returns #f, the build is considered to have failed.
EXP is built using GUILE-FOR-BUILD (a derivation). When GUILE-FOR-BUILD is
omitted or is #f, the value of the `%guile-for-build' fluid is used instead.
