# This Makefile fragment is intended to be included by packages that
# install Lua modules.
#
# === Package-settable variables ===
#
# LUA_LINKER_MAGIC
#	This appends LDFLAGS to properly link Lua modules on non-ELF
#	linkers.
#
#	You probably want to set this to "no" if the package links
#	binaries that are not Lua modules.
#
#	Possible values: yes no
#	Default: yes
#
# LUA_USE_BUSTED
#	Use busted to run tests and provide a do-test target.
#
#	Possible values: yes no
#	Default: no
#
# LUA_BUSTED_ARGS
#	Arguments to pass to the busted command when LUA_USE_BUSTED.
#
# === Defined variables ===
#
# LUA_LDIR
#	Path where Lua modules are installed.
#
# LUA_CDIR
#	Path where Lua C modules are installed. Not defined if
#	NO_BUILD variable is set to "yes".
#
# LUA_DOCDIR
#	Path where documentation files are installed.
#
# LUA_EXAMPLESDIR
#	Path where example files are installed.
#
# Keywords: lua
