+# This script is used to create the src.conf.5 man page, using template text
+# contained herein and the contents of the WITH_* and WITHOUT_* files in the
+# same directory. Each WITH_* and WITHOUT_* file documents the effect of the
+# /etc/src.conf knob with the same name.
+#
+# This script invokes "make showconfig" for each supported architecture in
+# order to determine, for each option, whether the default setting is always
+# WITH, always WITHOUT, or is architecture-dependent. It also determines
+# and describes dependencies between options.
+#
+# Usage:
+#
+#     cd tools/build/options
+#     sh makeman > ../../../share/man/man5/src.conf.5
