Latest __FREEBSD__ value for each release

[Dan Langille]

Hi folks,

For an upcoming FreshPorts project, I want to extract the latest 
value for __FREEBSD__ for each branch.  I'm hoping someone can save 
me some time and write a small perl script for me.  Thanks.

Given the release tags for the 4, 5, 6, and 7 branches[1], grab 
src/sys/sys/param.h from cvsweb[2], and grep for __FreeBSD_version.

What I need printed out on a single line is something like this.

4 492100
5 504104
6 600100
7 700006

Try starting with something like this:

my %Branches = ('HEAD' => 7, 'RELENG_6' => 6, 'RELENG_5' => 5, 
'RELENG_4' => 4);

Thank you.
