+# Default install prefix follows the host OS convention (override on the
+# command line: `make PREFIX=...`):
+#   illumos, Solaris (uname -s = SunOS):  /opt/party
+#   Linux, *BSD, macOS, everywhere else:  /usr/local
+# POSIX make has no ifeq or $(shell), so the OS dispatch lives in the
+# install/uninstall recipes themselves. BINDIR and MANDIR remain
+# independently overridable. Plain `=` rather than `?=` keeps illumos
+# /usr/bin/make happy (it predates POSIX-2008's conditional assignment).
+#
+# Beyond copying files, `make install` also wires the install bindir into
+# the system PATH so `party` and `man party` work from a fresh login shell
+# without -M or rc-file edits. The wiring is done by tools/post-install.sh
+# and is OS-aware: on illumos /opt/party is appended to /etc/default/login;
+# on Linux/BSD/macOS at /usr/local nothing needs doing; for non-standard
+# prefixes elsewhere the script prints the export lines to add manually.
+# `make uninstall` reverses the wiring symmetrically. Both steps are
+# skipped when DESTDIR is set (package staging context).
