+# This file is included by bsd.pkg.mk.
+#
+# Package-settable variables:
+#
+# EMUL_MODULES.${EMUL_OPSYS}
+#	List of modules of ${EMUL_OPSYS} that are used by the package.
+#
+#	Default value: undefined
+#
+# EMUL_PKG_FMT
+#	Binary emulation packaging format requested by the package.
+#	Possible values: any format listed in ${_EMUL_PKG_FMTS}.
+#
+#	Default value: plain
+#
+# Variables defined by this file:
+#
+# EMULSUBDIRSLASH
+#	Expands to either ${EMULSUBDIR}/lib or just lib depending on
+#	whether EMULSUBDIR is empty or not.  It is meant to be used
+#	in PLISTs and files where one wants to avoid "//" artifacts,
+#	e.g., ${EMULSUBDIRSLASH}lib.
+#
+# Public targets:
+#
+# emul-fetch
+#	This is a public target that fetches the distfiles for all
+#	supported EMUL_PLATFORMs.
+#
+# emul-distinfo
+#	This is a public target that generates a new distinfo file
+#	that contains checksums for all supported EMUL_PLATFORMs.
+#	This target should be run after the successful completion
+#	of the ``emul-fetch'' target.
+#
+
+# If we're doing true binary emulation, then file paths found in the
+# package's binaries, libraries and scripts won't necessarily match the
+# actual paths on the file system, so skip some path checks that are
+# likely to fail.
