 I. A FEW POINTERS
II. DOCUMENTATION

  For an overview of the Subversion project, visit

     https://subversion.apache.org/

  Once you have a Subversion client you can get the latest version
  of the code with the command:

     $ svn co https://svn.apache.org/repos/asf/subversion/trunk subversion

  The main documentation is the Subversion Book - an on-line version
  can be found at:
  
     https://svnbook.red-bean.com/

  It is written in DocBook XML, and the sources can be found at:

     https://svn.code.sf.net/p/svnbook/source/trunk/
     
  If you wish to build the documentation from source, read the
  en/README file within the book source.

  First, read https://subversion.apache.org/docs/community-guide/
  It describes Subversion coding and log message standards, as well
  as how to join discussion lists.

  Read the FAQ:  https://subversion.apache.org/faq.html

  See the final section of the first chapter of the Subversion Book.

  If you're a CVS user trying to move your CVS history over to
  Subversion, then be sure to visit the 'cvs2svn' project:

     https://github.com/mhagger/cvs2svn

  If you are running a Linux or BSD-based system, your distribution
  might have a cvs2svn package.

  If cvs2svn doesn't meet your needs, you might try refinecvs
  written by Lev Serebryakov:

    http://lev.serebryakov.spb.ru/refinecvs/

  Please note that cvs2svn and refinecvs are *separate* projects
  from Subversion.  If you have problems or are confused, contact
  the authors, not the Subversion lists.

  Finally, be sure to see Appendix B in the Subversion Book.  It
  contains a very quick overview of the major differences between
  CVS and Subversion.
