GPG scripting for muttrc

[Gary]

Hello all, 
I have just switched over to GPG instead of PGP, as PGP 6.52 would not
work properly.  The new GPG installed well, but I cannot get is
properly scripted (for a lack of knowledge) in my muttrc file.  

Can someone help, or point me in the right direction for a sample
script on line?  Could not find any references in the sample rc files
on line.  

Thanks for your help,

Regards,
Gary
