# ---------
# ~ legend
# (a) - append more data if needed
# (n) - do not override without a good reason
# (y) - override as appropriate per ebuild
# Build general GNUstep ebuild depends here
# - most .app should be set up this way:
#   + (a) DEPEND="${GS_DEPEND} other/depend ..."
#   + (a) RDEPEND="${GS_RDEPEND} other/rdepend ..."
# - core libraries and other packages that need to
#     specialize more can use:
#   + (n) DOC_DEPEND - packages needed to build docs
#   + (n) GNUSTEP_CORE_DEPEND - packages needed to build any gnustep package
#   + (n) GNUSTEP_BASE_DEPEND - packages needed to build gnustep CLI only apps
#   + (n) GNUSTEP_GUI_DEPEND - packages needed to build gnustep GUI apps
#   + (n) DEBUG_DEPEND - packages needed to utilize .debug apps
#   + (n) DOC_RDEPEND - packages needed to view docs
