# Builder for depot-internal Emacs packages. Packages built using this
|
||
|
|
# builder are added into the Emacs packages fixpoint under
|
||
|
|
# `emacsPackages.tvlPackages`, which in turn makes it possible to use
|
||
|
|
# them with special Emacs features like native compilation.
|
||
|
|
#
|
||
|
|
# Arguments passed to the builder are the same as
|
||
|
|
# emacsPackages.trivialBuild, except:
|
||
|
|
#
|
||
|
|
# * packageRequires is not used
|
||
|
|
#
|
||
|
|
# * externalRequires takes a selection function for packages from
|
||
|
|
# emacsPackages
|
||
|
|
#
|
||
|
|
# * internalRequires takes other depot packages
