netsim.spec

# PyInstaller spec — single-file `netsim` binary (Linux) / netsim.exe (Windows).
#
#   pip install pyinstaller
#   pyinstaller netsim.spec            # -> dist/netsim   (or dist/netsim.exe)
#
# The examples/ dir is bundled as data so `netsim run mN` works inside the
# frozen binary. matplotlib is NOT collected by default (keeps a local build
# small + the stdlib demos work everywhere); build with NETSIM_WITH_PLOTS=1
# to fold matplotlib/pillow in for the viz/plots/gif demos. The CI release
# binaries ARE built with NETSIM_WITH_PLOTS=1, so the published downloads have
# the plotting demos working out of the box (at the cost of a larger file).
