Well it's not exactly complete ;-) Basically on the RISC OS side
the directory structure looks like:

  OSLib [project root]
  + Build [build area for intermediate files]
    + Help
    + Release
    + Release26
  + OSLib [final output area]
    + o
    + OSLib
      + h
      + Hdr
  + Source [source files]
    + !Help [taskobey file to build help files]
    + !Release [taskobey file to build 32 bit OSLib]
    + !Release26 [taskobey file to build 26 bit OSLib]
    + HelpMF [template for makefile to build help files]
    + TemplateMF [template for makefile to build oslib]
    + Source [cvs/svn checkout nfs mounted from linux box]

The template makefiles are processed by a program I wrote called
makegen that does roughly what the makatic tool from Dr Smith's
used to do - mine is 32 bit clean though, so works on the Iyonix, and
it also has some bugs/limitations fixed.

I've attached the taskobey files and the template makefiles.

The NFS mount is not actually of the checkout itself, but of a link
farm created to "flat out" the checkout by dropping the distinction
between the four different groups of SWIs that exists purely to work
around the 77 file limit in old RISC OS versions. The shell script
that I use to build this link farm is also attached.

All this assumes that defmod and things are already build and sitting
in my library directory - I've never got arround to converting them
to use makegen.
