# Notes:
#  - fmod support is based on an old version of fmod which is not in portage,
#    and therefore not supported by this ebuild. SDL is the preferred library.
#  - Have contacted upstream requesting overridable build variables and a
#    configurable config file path, to obviate file editing in src_prepare.

# Regarding licenses: libgarglk is licensed under the GPLv2. Bundled 
# interpreters are licensed under GPLv2, BSD or MIT license, except:
#   - alan2/alan3: status unclear!
#   - glulxe: custom license, see "terps/glulxle/README"
#   - hugo: custom license, see "licenses/HUGO License.txt"
# Since we don't compile or install any of the bundled fonts, their licenses
# don't apply. (Fonts are installed through dependencies instead.)
