where are the git to svn export script(s) please ?

Hi current@freebsd.org
cc ctm-users@freebsd.org

Has git to svn exporter stopped for src-12 ?
	https://svnweb.freebsd.org/base/stable/12/
Closure of ports from svn was mentioned long ago for ports@ at:
	https://www.freebsd.org/developers/cvs/
But no mention of src-12, src-cur & svn tree itself.

Reason for asking:
The CTM (src[*], ports & svn patches for freebsd.org sent by mail) generator
runs on host http://ctm.berklix.org, using a lot of inherited opaque
scripts that use svn. 

Rather than lose more time trying to understand those scripts &
convert them to call git, it might be quicker for me to copy the
git to svn export script(s) & run export from git to svn on host
ctm.berklix.org ?

Where are the git to svn export scripts & crontab sample invocations please ?

Cheers,
