+# yhttpd — Docker build (revival)
+#
+# yhttpd is a minimal httpd derived from ychat's socket/engine. This image
+# builds it entirely in a container on Rocky Linux 9 (its bespoke perl build
+# system was gated to g++ 3.x; the configure now accepts any GNU g++).
+#
+# NCURSES and CLI are disabled (glob.h) so the build needs no ncurses and
+# produces a pure httpd. The server listens on port 2000 (httpd.serverport).
+#
+# STATUS: with the ported fixes yhttpd now BUILDS on a modern toolchain and
+# serves requests without crashing when built+run here (Rocky Linux 9 /
+# GCC 11). A SIGILL heap-corruption crash in sock::_close DOES reproduce
+# when built on a newer host toolchain (GCC 16) - see yhttpd/DOCKER.md for
+# why this doesn't mean it's fixed. Concurrent bursts still see some
+# connection resets (not crashes). See yhttpd/DOCKER.md for details.
