# --enable-pygwy is Python 2.7 only (upstream requirement). pygwy's
# C bindings need the python gobject/gtk/gtk.gdk modules at runtime;
# the bundled modules/pygwy/pygtk-embed only ships build-time headers
# and codegen, not the runtime CPython bindings, so system pygtk:2
# (which pulls pygobject:2 and pycairo-python2) is required for a
# working 'import gwy'.

# Building from SVN regenerates the pixmap PNGs from src/*.svg at build
# time (release tarballs ship them pre-built). We rewire the rules in
# src_prepare to call rsvg-convert directly instead of inkscape so this
# is a much smaller dep -- not pulled in for 2.70/2.71.
