Migration to subversion

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Hello PARI-dev,

We are half-done with the subversion migration. At this stage
we provide:

--  Anonymous read-only CVS access (same as usual)
-- A web SVN gateway (similar to the old web CVS gateway)
-- read/write SVN access for registered PARI developers.

Change to the SVN repository are automatically reported to the old CVS
repository.

   ** If you are a registered PARI developer **

 If you have repositories with read/write CVS access, do not use them to
commit anymore. Convert them to subversion first. I cannot prevent you
to write to the CVS repository without also preventing you to read it,
which would be very inconvenient for you.

 To import the a read/write SVN repository do 
 svn co 'svn+ssh://<login>@pari.math.u-bordeaux.fr/home/svn/pari/trunk'
 It will be named trunk.
 You can use 'cvs diff -u' to extract the uncommited chnage in your CVS
 repository and 'patch' to apply them to you SVN repository.

   *********************************************

The next stage is to update the documentation to update and provide an
anonymous read-only SVN access. 

Cheers,
Bill.
