[ooo-build] new ooo-build workflow for developers and packagerts

[Petr Mladek]

Hi,

there is still confusion how to use ooo-build after we started to move
the diffs to git.

It is clear that developers and packagers has a bit different needs. I
tried to describe the current suggested workflow at 
http://www.freedesktop.org/wiki/Software/ooo-build/BuildingIt#Buildingfordifferentpurposes


There are currently two FIXME's:

1. I think that --with-git=/path-to-another-clone-dir should cause
   that the other clone is used as reference to create the new clone;
   the new clone still should push directly to freedesktop.

   Is this true? Kendy, Thorsten?

2. I think that --with-tag option does not longer make sense. If you
   want to use another ooo sources, you should use the new
   --with-source-version option that is more descriptive

   I am going to remove the --with-tag option


Feel free to suggest a better workflow. Point out problems with the
current one, ... Add more tips, e.g. the Fridrich's --with-src dir, ...

BTW: I think that we can't longer support build of pure OOo sources. I
think about to remove the related things from configure/download/unpack
to make them a bit easier.


Best Regards,
Petr
