kernel-doc-nano-HOWTO.txt has a chapter about man pages
production. While we don't have a working "make manpages"
target, add it.

+How to use kernel-doc to generate man pages
+-------------------------------------------
+
+If you just want to use kernel-doc to generate man pages you can do this
+from the Kernel git tree::
+
+ $ scripts/kernel-doc -man $(git grep -l '/\*\*' |grep -v Documentation/) | ./split-man.pl /tmp/man
+
+Using the small ``split-man.pl`` script below::
+
+
+ #!/usr/bin/perl
+
+ if ($#ARGV < 0) {
+ die "where do I put the results?\n";
+ }
+
+ mkdir $ARGV[0],0777;
+ $state = 0;
+ while (<STDIN>) {
+ if (/^\.TH \"[^\"]*\" 9 \"([^\"]*)\"/) {
+ if ($state == 1) { close OUT }
+ $state = 1;
+ $fn = "$ARGV[0]/$1.9";
+ print STDERR "Creating $fn\n";
+ open OUT, ">$fn" or die "can't open $fn: $!\n";
+ print OUT $_;
+ } elsif ($state != 0) {
+ print OUT $_;
+ }
+ }
+
+ close OUT;
