# patched https://packages.debian.org/stretch/w3m
#
# 2026/07/27 Ioannis Anagnostakis: switched upstream from the dormant Debian
#   fork (tats/w3m, last touched 2023) to Rene Kita's actively maintained
#   fork at https://sr.ht/~rkta/w3m, (not gemini) which is where w3m development lives
#   now for most distros.
