How to build from a github checkout ?

[Norm Green]

Hi,

We are mirroring the krb5 code from github and I've noticed certain 
build files are missing, most importantly 'configure'.

The wiki page (http://k5wiki.kerberos.org/wiki/Building) says to run 
.src/autorecof to generate the build scripts, but I don't see the file 
.src/autoreconf in my checkout either.
Perhaps the wiki is out of date?

Can someone please tell me how to generate configure from a github checkout?

thanks,

Norm Green
