Sync Ports to Packages

[mfv]

Hello,

Am trying to write a script to keep my packages and ports in sync but
have not been able to find a local file in the package system that
contains the revision number of my last upgrade.  Once that number is
obtained it is possible to sync the port tree.

The following script extracts the build number from the appropriate
server but needs Internet access:

Is it possible to extract the same revision number from a local file?

Any leads would be appreciated.

    Cheers ...                                 __o
