busybox.htm already has anchors inserted for each command of the form "item_command".
All you have to do is edit /usr/bin/man and change line 46 (as of 2.12) to
Code: Select all
exec dillo file://usr/share/doc/busybox.htm#item_${1}
BTW busybox.htm is not valid XHTML strict or even transitional. In fact it is not even valid XML. I presume the file is exactly what is supplied by the project.
