commit da4121067329547fcbb9b1765c65f884599b2631
Author: Eric Blake <address@hidden>
Date:   Wed Mar 7 10:47:01 2012 -0700

    build: require perl 5.6
    
    This reduces the implicit requirement from 5.6.2 back to 5.6,
    while raising the explicit requirement to match the actual code.
    
    * configure.ac (PERL): Fail up front if perl is too old.
    * NEWS: Document this.
    * README: Likewise.
    * README-hacking: Likewise.
    * lib/Autom4te/ChannelDefs.pm: Bump requirement.
    * lib/Autom4te/General.pm: Relax requirement.
