# Although it is listed in INSTALL.OCTAVE as a build tool, Octave runs
# "makeinfo" from sys-apps/texinfo at runtime to convert its texinfo
# documentation to text (see scripts/help/help.m).
#
# (un)zip isn't mentioned, but there's a test that uses it (bug #775254).
#
# The use of USE=imagemagick to pull in media-gfx/graphicsmagick is not
# ideal, but both "graphicsmagick" and "imagemagick" are global USE
# flags whose existing descriptions conflict with the obvious way we
# would want to use them in octave. In any case, upstream doesn't really
# support imagemagick, only graphicsmagick (bug 864785).

# There are three ways to plot in Octave:
#
# 1. The old gnuplot renderer
# 2. The OpenGL renderer using the FLTK backend
# 3. The OpenGL renderer using the Qt backend
#
# It's possible to use the Qt GUI without OpenGL, but OpenGL rendering
# is all that FLTK is used for, so it doesn't make sense to enable
# USE=fltk without USE=opengl.
#
# Building without either USE=gnuplot or USE=opengl is technically legal,
# but will leave you unable to plot anything.
#
# Octave's FLTK support is unofficially deprecated, in the sense that
# you'll often get "why are you using FLTK?" in response to
# bugs. (Upstream bug 59321 for a random example.) In the future, it
# will probably make sense to merge USE=opengl and USE=X into USE=gui,
# dropping USE=fltk entirely.
