Weirdness in the makefile

[Scott Ritchie]

Can someone explain the significance of these targets in the makefile:

manpages:
    $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/man3w
    cd dlls && $(MAKE) man

htmlpages:
    $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/html
    cd dlls && $(MAKE) doc-html

sgmlpages:
    $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/api-guide
    cd dlls && $(MAKE) doc-sgml

Do they do anything?  Those don't seem to be valid directories anymore.

Thanks,
Scott Ritchie
