+# The platforms that are supported by pkgsrc differ in the amount of
+# functions they provide in the C library (libc). Functions that are
+# typically available on NetBSD are provided in the libnbcompat package.
+#
+# This file defines a set of "features" that some packages require.
+# Whenever a package makes use of them, it should list the features in
+# the USE_FEATURES variable. (It serves a similar purpose as USE_TOOLS.)
+#
+# The *.c files that use the features must be patched a little. When
+# there are missing features, the C preprocessor macro HAVE_NBCOMPAT_H
+# will be defined to 1. In this case, the headers from the nbcompat
+# directory must be included.
+#
+# === Example ===
+#
+# In the package Makefile:
+#
+#	USE_FEATURES=		err
+#
+# In the C files using the err*() or warn*() functions:
+#
+#	#if defined(HAVE_NBCOMPAT_H)
+#	#include <nbcompat/config.h>	/* needed for the other headers */
+#	#include <nbcompat/cdefs.h>	/* needed for the other headers */
+#	#include <nbcompat/err.h>
+#	#else
+#	#include <err.h>
+#	#endif
+#
+# === Package-settable variables ===
+#
+# USE_FEATURES
+#	Lists the system features required by the package.
+#
+#	Possible:
+#	* asprintf: The functions asprintf and vasprintf.
+#	* cdefs: The header sys/cdefs.h.
+#	* err: The functions err, verr, errx, verrx.
+#	* warn: The functions warn, vwarn, warnx, vwarnx.
+#	* fts_close, fts_open, fts_read, fts_set: Functions
+#	  for filesystem traversal.
+#	* getopt_long: The GNU version of getopt.
+#	* getprogname, setprogname
+#	* glob
+#	* regcomp
+#	* snprintf, vsnprintf
+#	* utimes
+#	* nbcompat: All of the above.
+#
+#	Default value: undefined
+#
+# === Variables defined by this file ===
+#
+# MISSING_FEATURES
+#	The features listed in USE_FEATURES that are missing on the
+#	current system.  Also includes "inet6" if the system doesn't
+#	support IPv6.
