# 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).

# bash, mksh, ksh) honors them and rewriting through stat would be a
