Please see lberk/dev on git://sourceware.org/git/pcpfans.git

and the opensuse build issue Ken was seeing.

Cheers,

Lukas

    spin-rawhide: Extract version info from VERSION.pcp
    
    At times (specifically after a release), the spec file can become out
    of sync with the VERSION.pcp.  This tweak of spin-rawhide gets the
    specific version info from the definitive source (VERSION.pcp).
