Which Perl package is used can be specified with @code{#:perl}.
@end defvr
@defvr {Scheme Variable} renpy-build-system
This variable is exported by @code{(guix build-system renpy)}. It implements
the more or less standard build procedure used by Ren'py games, which consists
of loading @code{#:game} once, thereby creating bytecode for it.
It further creates a wrapper script in @code{bin/} and a desktop entry in
@code{share/applications}, both of which can be used to launch the game.
Which Ren'py package is used can be specified with @code{#:renpy}.
Games can also be installed in outputs other than ``out'' by using
@code{#:output}.
@end defvr
@defvr {Scheme Variable} qt-build-system
This variable is exported by @code{(guix build-system qt)}. It
is intended for use with applications using Qt or KDE.
