+# Validation of cross references with mandoc -Tlint only looks
+# for manual pages in the following directories:
+
+MANPATH_BASE="/usr/share/man:/usr/X11R6/man"
+
+# When man(1) is called with the -S option and no manual page is
+# found matching the requested name and the requested architecture,
+# it tries to figure out whether the requested architecture is valid
+# for the present operating system. Normally, ./configure detects
+# the operating system using uname(1). If that fails or is not
+# desired, either of the following lines can be used:
+
+OSENUM=MANDOC_OS_NETBSD
+OSENUM=MANDOC_OS_OPENBSD
+OSENUM=MANDOC_OS_OTHER
