    The file vetags-patch contains a patch to etags.c (coming with 
    the GNU emacs distribution) to extract tag-information from	
    AtFS versions.


What is does:

    This file turns etags into vetags, a version sensitive variant 
    of emacs' tags program etags. Etags normally resides in
    <emacs-home>/etc. Vetags behaves just as as etags, with the 
    extension that taggification can be applied to versions of files
    (as opposed to just plain files) that are stored in the AtFS
    version object base. Which version of the source files are analyzed
    is determined by the ``vbind'' options that can be passed from the
    command line.

    For further information refer to the manual pages of etags(1)
    and vbind(1).


How to apply the patch:

    Unpack the GNU Emacs distribution. This should create a directory
    named "etc".  Copy the file etags.c from this directory into
    <shapeTools-Home>/src/patches, and change to this directory.

    Type "make vetags". Voila !

    The patch is known to work with the version of etags.c that
    comes with emacs-18.59. No warranty for emacs-19.* versions of
    etags.
