Re: Raw doc in the policy group files

Hi Hugh,


What do you think of this to replace the first section of policygroups.html?
Does it say all that needs saying by way of introduction, or does it 
require more fleshing out?


   Policy  Groups are an elegant general mechanism to configure FreeS/WAN
   IPsec. They are useful for about 95% of IPsec applications.

   In  the  1.x  configuration model, in order to build IPsec connections
   between  pairs of nodes, you needed to configure a connection for each
   pair.  This  made  IPsec  configuration an n-squared affair, and often
   resulted in long, complex /etc/ipsec.conf files.

   By  contrast,  Policy  Groups  allow you to set local IPsec policy for
   lists  of  remote  CIDRs  (names,  IPs  or  groups  of IPs), simply by
   mentioning  the  CIDR  in  the  approriate  Policy  Group  file. Linux
   FreeS/WAN  then  internally creates the connections needed to
   implement that policy.

   In the next section we describe our five Base Policy Groups, which you
   can use to configure IPsec in many useful ways.



Cheers,

Claudia
