#
# Example configuration to enable HTTP access for a directory
# containing Subversion repositories, "/var/www/svn".  Each repository
# must be both:
#
#   a) readable and writable by the 'apache' user, and
#
#   b) labelled with the 'httpd_sys_content_t' context if using
#   SELinux
#

#
# To create a new repository "http://localhost/repos/stuff" using
# this configuration, run as root:
#
#   # cd /var/www/svn
#   # svnadmin create stuff  
#   # chown -R apache:apache stuff
#   # chcon -R -t httpd_sys_content_t stuff
#

#<Location /repos>
#   DAV svn
#   SVNParentPath /var/www/svn
#
#   # Limit write permission to list of valid users.
#   <LimitExcept GET PROPFIND OPTIONS REPORT>
#      # Require SSL connection for password protection.
#      # SSLRequireSSL
