regex for finding all ports using the cxx11 1.0 PG and changing them en-masse to the cxx11 1.1 PG

[Ken Cunningham]

It seems that there is no reason for a port to still be in the cxx11 1.0 PG.

I stumble across them from time to time still.

Do any of the regex-masters have an easy way to find all the cxx11 1.0 PG 
entries and change them all to 1.1 PG?

Thanks, 

Ken
