[DAS2] updated DAS/2 spec files

[Andrew Dalke]

I've updated the spec in CVS.  Here are the changes:

- folded in the various changes I brought up last month
("PROPERTY-LIST" -> "PROPERTIES"; RFC dates -> ISO dates; etc.)
Lincoln said yes to all the changes.

- results of the template file are now saved to "das2_get.html"
Given what Steve said today this means the web site should be
updated to this version next time the cron is run

  - added a README describing how the spec is made from the
template.

Note: You can edit the spec directly as a normal HTML file.
The templating language I use is ZopePageTemplates (also
called "TAL") which extends HTML only through attributes.
This are ignored by browsers so if Gregg wants to modify
things, go right ahead.

   - checked ZopePageTemplates and ElementTree into CVS
under the das/das2 directory.  These are Python libraries
used by the template processor program "convert_template.py"
I checked them in so anyone can assemble the template from
that directory doing either

   make

or

   python convert_template.py das2_get_template.py das2_get.py

I have verified that you can build the final "das2_get.py"
from the template file on the open-bio machine "pub.open-bio.org"
using the current setup.


NOTE: If you change the RELAX-NG RNC files you'll need
to rebuild the RNG and DTD files, and you'll need to
configure the TRANG variable in the Makefile to point to
your local copy of trang.  I did not attempt to make this
easy for someone who isn't on a unix machine.  On unix
the dependencies are rebuilt as part of the normal "make"

NOTE: If you want to run the schema validation regression
tests you must set the Makefile's JING variable to your
local copy of java and jing.  Then you can do "make verify"
