icc profiles in gs 8.70? xefitra

Is icc color management available in Ghostscript 8.70 for win32?  I
would like to specify a default RGB input profile, default CMYK output
profiles, perceptual rendering intent and ensure that any embedded
profiles are disregarded.  The input pdf files will contain RGB and/or
CMYK and output will be CMYK tiff.  CMYK values should pass through
unchanged - as they do now.

There seems to be lot of work being done for icc support and there was a
comment about -sDefaultRGBProfile and -sDefaultCMYKProfile parameters in
the icc_work branch.
http://www.ghostscript.com/pipermail/gs-cvs/2009-May/009318.html
The parameters had no effect when used with gs 8.70:

gswin32c -sDEVICE=tiff32nc -sOutputFile=CMYK.tif
-sDefaultRGBProfile="AdobeRGB1998.icc"
-sDefaultCMYKProfile="GRACoL2006_Coated1v2.icc" -r72 -dBATCH -dNOPAUSE
CMYK-and-RGB.pdf

Any suggestions or relevant info would be appreciated.

There will soon (within the next month I hope) be a beta version of
ghostscript available for the operations that you want.   This development
is taking place, as you noted, in the icc_work branch.  The goal is to be
able to merge this branch into the main trunk for the February release of
ghostscript.  A document that describes some of the work and features (it
probably needs to be updated yet again) is available in the main source tree

gs/doc/Color_Architecture.pdf

or

http://www.ghostscript.com/~mvrhel/Ghostscript_Color_Architecture.pdf

If you have any particular needs related to ICC color flow that you believe
this architecture does not address, please let me know.

Any port in a storm. I can convert from RGB to CMYK easily using
Imagemagick's convert program but that converts everything to a
bitmap. Not wonderful for text. I can convert to the near-
mandatory pdf x/1-a:2001 format (more and more USA digital
printers are specifying it) using the shareware progam
Pstill but that costs money and I don't know what if anything it
does to color models.  I can import into Scribus and export, which
handles color models but doesn't (yet) offer the PDF X/1-a format.

One of the goals of ghostscript is or was to make Acrobat Distiller
unnecessary for most of us.  Addressing color model and pdf
format questions mentioned above would be a big step toward
that goal.
