@end defvr
+@defvr {Scheme Variable} julia-build-system
+This variable is exported by @code{(guix build-system julia)}. It implements
+the build procedure used by @uref{https://julialang.org/, julia} packages,
+which essentially is similar to running @command{julia -e 'using Pkg;
+Pkg.add(package)'} in an environment where @code{JULIA_LOAD_PATH} contains the
+paths to all Julia package inputs. Tests are run not run.
+
+Julia packages require the source @code{file-name} to be the real name of the
+package, correctly capitalized.
+
+For packages requiring shared library dependencies, you may need to write the
+@file{/deps/deps.jl} file manually. It's usually a line of @code{const
+variable = /gnu/store/libary.so} for each dependency, plus a void function
+@code{check_deps() = nothing}.
+
+Some older packages that aren't using @file{Package.toml} yet, will require
+this file to be created, too. The function @code{julia-create-package-toml}
+helps creating the file. You need to pass the outputs and the source of the
+package, it's name (the same as the @code{file-name} parameter), the package
+uuid, the package version, and a list of dependencies specified by their name
+and their uuid.

@defvr {Scheme Variable} minify-build-system
This variable is exported by @code{(guix build-system minify)}. It
implements a minification procedure for simple JavaScript packages.
