@q Changes for CWEB in TeX Live from numerous contributors.              @>
@q This file is in the Public Domain.                                    @>

@q Most of the original Kpathsea changes by Wlodek Bzyl and Olaf Weber   @>
@q were merged with the set of change files of the CWEBbin project;      @>
@q see https://github.com/ascherer/cwebbin for the original parts.       @>

@q This stripped change file {comm,ctang,cweav,ctwill,cwebman}-w2c.ch    @>
@q has been created from the elaborate set of change files               @>
@q {comm,ctang,cweav,cwebman}-patch.ch,                                  @>
@q {comm,cweav,cwebman}-extensions.ch, {comm,ctang,cweav}-output.ch,     @>
@q {comm,ctang,cweav}-i18n.ch, and cweav-twill.ch for CTWILL, and        @>
@q {comm,ctang,cweav,ctwill,cwebman}-texlive.ch with the 'tie' processor @>
@q and is used as a monolithic changefile for {common,ctangle,cweave}.w  @>
@q and cwebman.tex in TeX Live.                                          @>

@q Please send comments, suggestions, etc. to tex-k@@tug.org.            @>
