Changes between Initial Version and Version 1 of Ticket #4486, comment 5

initial	v1
4	4	* The plugin writes to `packages.pth` in the egg in response to a POST request. I don't think we can assume that the web server will have write access to the egg.
5	5
6		We do need a way to pass environment variables to the hook scripts, which has always been a problem with Subversion since the hooks run in an empty environment. Subversion 1.8 has a [https://subversion.apache.org/docs/release-notes/1.8.html#hooks-env configuration] for hook script environment variables. I think we could eliminate `svnpolicy.conf` and `hooks/packages.pth`, and ~~the~~ instruct the user how to configure the hooks environment in Subversion 1.8 and later. Subversion 1.8 seems like a reasonable requirement since it was released in June 2013.
