miext/rootless was just an example.

I'm not importing them.  That's part of the point: others are working on 
that tree as well, and hopefully more will in the future.  That lessons 
my work load for keeping in sync when it is required.

Of course, I have some new features that I will be working on that will 
not be sent to XFree86.  They will go only to the freedesktop.org trees 
and anyone that builds from those trees can use those new features.  Of 
course, I won't stop people from importing those patches to XFree86, nor 
will I require they put my name in documentation, but none of that 
really matters.

Another example would be that Alexander Gottwald just fixed some 
fundamental brokeness related to FD_SETSIZE and XFD_SETSIZE; that patch 
was committed directly to the xorg tree rather than being ignored on the 
XFree86 patch queue for two months.  Again, anyone that builds from the 
freedesktop.org tree will have that generic fix.

There was a difference: the version on freedesktop.org is the canonical 
version of the Cygwin/X source; if something is not in that tree, then 
it will not be in the next release; bugs present in the fd.o tree are 
exactly those bugs that will be in the next release (when I start 
cutting releases from that tree soon).  This is as opposed to the 
XFree86 and SourceForge trees: bugs present in each tree were different, 
particularly from the 4.3.0 branch used for building distributions; 
features present in the two trees were different.

When someone wanted an exact debug build of the current release, the 
only way to do it was to grab the 4.3.0 branch from XFree86, then apply 
the Cygwin-specific changes that had not been merged.

Could I have possibly done this at SourceForge?  Sure, but what is the 
bloody point of now keeping in sync with HEAD and xf-4_3-branch? 
Remember, I didn't get into this project to be a cvs lacky, I got into 
it because I enjoy coding.  Forcing me to keep an alternate tree in sync 
for no good reason was pretty much the ultimate insult; there was the 
ability to lesson my work load on such trivial, but time consuming, 
things; however, my request to do so was met with refusal.

Of course, I am responsible for my own interpretations.  I'm not sure if 
you have been following the Cygwin/X project lately, but I think you at 
least know that we are no longer associated with XFree86.  Given that, 
we needed a new canonical tree, or upstream tree, which is what the 
freedesktop.org tree is.  So, for you to ask why I wasn't committing to 
our SourceForge tree instead of fd.o seemed a little silly.

I can understand that seeing the documentation still being updated in 
the SourceForge tree would be a little confusing, which is why the 
documentation should be moved to fd.o and the SourceForge project should 
be deleted.  I think everyone agrees on that; it just hasn't been done yet.
