# Purpose: an exlib dealing with installation of the love engine
# Maintainer: Julian Ospald <hasufell@posteo.de>
# Exports: src_prepare src_install
# Side-effects: - adds build and runtime dependencies
#               - sets $SUMMARY, $HOMEPAGE, $DOWNLOADS, $LICENCES,
#                      $DEFAULT_SRC_CONFIGURE_PARAMS,
#                      $DEFAULT_SRC_INSTALL_EXTRA_DOCS,
#               - imports alternatives, lua, bitbucket
#                         autotools depending on $LOVE_AUTOCONF
#
# Usage
#   Set LOVE_AUTOCONF before 'require' to force autoreconf
