        !             2: We will now convert your existing uucp configuration to those required
        !             3: by this implementation of Taylor uucp. This is not a destructive process.
        !             4: Before existing files are overwritten, you will be given the opportunity
        !             5: to save them to a tarred archive.
        !             6: 
        !             7: The conversion process consists of building new Taylor uucp configuration
        !             8: files from the data in your existing files, saving your old uucp files
        !             9: to a tarred archive and finally copying the new files into place. The
        !            10: conversion of the existing data files may have problems if you are performing
        !            11: undocumented functions with the existing uucp facilities. For example,
        !            12: if you have multiple entries for a single uucp site in L.sys, you may
        !            13: not achieve the expected results with this conversion. If you run special
        !            14: shell scripts to swap L-devices with other files, which some COHERENT users
        !            15: have done in order to use multiple modems on their systems, this conversion
        !            16: process will only deal with the existing L-devices file. This means that the
        !            17: data from the other files used to swap with L-devices will not be accounted
        !            18: for.

        !            20: If, while running the conversion process you notice messages that indicate
        !            21: potential problems, write them down. If necessary, you can always re-run this
